Pec Flex

LaBarbara: You can't argue with those luscious pecs!
Hermes: No I can't. But I can ask him to stop wiggling them in my face!
Barbados Slim: I'm not wigglin' dem. Dey do dat by demselves.

Similar to Gainaxing, where a male character's pectoral muscles jiggle and bounce, except that they flex them to make it happen. However, generally it is used not so much for Fanservice as it is used as an often comedic demonstration of "manliness". Other names for it are the "Pec Bounce", the "Pec Dance" (usually this name is used if people flex their pecs in time to music), and the "Pec Pop".

Another variant is the "Ab Wave", where a character with a well defined six pack will flex their stomach muscles like a wave. Generally, this isn't so much saying "look how strong I am" as it is "aren't I sexy?"

For cases of Pec Flex when the flexer has less than impressive pecs, see Flexing Those Non-Biceps.

    Literature 
  • "Slayers''
    ''I wanna do that! But I can't!"
    • It is worth mentioning that this line appears when Lina Inverse sees the "Dragon Blood Macho Battlers". A gang of bandits whose STANDARD GREETING apparently is to flex and twitch their pecs.

    Films — Animated 
  • This is done by Young Macintosh in Brave, in his attempt to impress Merida during the suitor presentation.
  • In Moana, Maui does this at the beginning of his "I Am Great!" Song. Even better, he flexes each pec one after the other, bouncing his Animated Tattoo across his chest! "I know it's a lot, the hair the bod / When you're staring at a demigod!"

    Video Games 
  • Slaking's Diamond/Pearl animation in Pokémon has it Pec Flex. Of course, they don't necessarily have to be male....
    • Machoke in Crystal, too. And Machamp in Black/White. Once again, one out of four is female...
  • A Super Robot Wars 4koma parodying Ibis Douglas having the least bouncy chest in the series gets epically ridiculous when Sanger Zonvolt shows up barechested and does this trope after having already shown one of the bustiest characters in the series and a loli outdoing her.
  • Super Macho Man from Punch-Out!! introduces himself before a fight with a Pec Flex.
  • Zangief did it in several iterations of Street Fighter, even the chibi-Zangief in Super Gem Fighter Mini Mix (or Pocket Fighter, depending on locale). And in Street Fighter V's story mode, he breaks a Psycho-powered sword in two just by doing this trope.
  • Leisure Suit Larry can do this after hitting the gym (a lot) in Leisure Suit Larry 3. The subtitle of the game is called Passionate Patti in Pursuit of the Pulsating Pectorials after all.
  • Undertale: Aron, one of the random encounters in Hotland, is a horse-headed monster who is always flexing. It's possible to end battles against him non-violently by engaging in a flex-off with him until he flexes himself right out of the battle screen.

    Web Original 
  • Gaia Online's Halloween 2007 vampire attack event had the Von Helson Twins ordered to kill Liam. Liam seduced the twins by flexing and spouting hilariously bad come-ons, which saved his life (and scored him a threesome) but left him a couple of stalkers.
  • From the Planet Fitness Clunk-A-Lunk game, we have Pecadoodledude.
    Meet Pecadoodledude! You know this guy. He's the narcissistic nimrod who's always parked in front of the mirror, pausing between sets to lift up his shirt and peep his almighty pecs! He'll make 'em bounce! He'll make just the right one go! And then just the left! And then he'll juggle them back and forth! You'll wish that he'd knock himself out with one of his considerable chesticles! But he won't. He'll just keep checking himself out. So clunk away, my friend. Clunk away.
    • At least to this troper, it kinda sounds like the narrator keeps complimenting the guy.
  • In this video, two guys use this trope as a form of morse code.
  • One guy turned this trope into a language.
  • Marc Lobliner from Tiger Fitness does this in almost every video.
  • One guy bounced his pecs to the Harlem Shake for about 7 minutes.

    Western Animation 
  • The Fairly OddParents:
    • There are two characters that do this. Juandissimo Magnifico, Wanda's ex-boyfriend, does this along with his constant magic shirt ripping. Also, in the Made-for-TV Movie Abra-Catastrophe, Cosmo gains massive pecs from a workout video, and he Pec Flexes to absorb Crocker's magic.
    • Who could forget Jorgen Von Strangle, toughest fairy in the universe. He loves to flex his muscles in the faces of anyone he can. He even refers to them as another sentient being (ex: "My muscles and I are still laughing!" Muscles: "Ha...haha...ha!"
    Crocker: Those are some massive pecs.
  • Johnny Bravo can juggle with his pecs as a party trick.
  • The Simpsons: Homer Simpson imagined himself doing this once while under the influence of Duff. Flexing them in time to the Can Can, too.
  • American Dad!: Stan Smith did the same thing as well when he was celebrating.
  • Lord Pain does this in The Grim Adventures of Billy & Mandy to show off his tattoos of Grim right in front of him.
  • An odd mechanical version done by Adonis in his Powered Armor in the Teen Titans episode "The Beast Within", right after he knocks Cyborg out at the beginning of the episode.
  • Time Squad: Buck bounced his pecs in a cartoon cartoon Friday crossover with Johnny Bravo.
  • Futurama has Barbados Slim, and his luscious pecs. They apparently wiggle by themselves.
  • Happens precisely once in Meet the Robinsons.
  • Young Macintosh from Brave does this in his introduction (here's the clip in question.)
  • This happens a few times in Regular Show.
    • Twice in "Rigby's Body", once by the bodybuilder that jumped into Rigby's body and again by Skips. His nipples light up.
    • Mordecai gets one too when he daydreams in "Meat Your Maker".
    • The episode "Bald Spot" features Muscle Man doing thisas a plot point. Specifically, he kept flexing his pecs (which translates in this case to jiggling his manboobs) throughout the entire episode in order to distract Starla from his bald spot on his head.
    • Rigby does this after he gets buffed up in "One Pull Up".
    • This also happens in two Cartoon Network bumpers of Regular Show where one's a fusion of Mordecai and Skips, and the other is two clips of "Rigby's Body" with Skips and "Meat Your Maker" with Mordecai when he daydreams back to back.
  • In the My Little Pony: Friendship Is Magic episode Rainbow Falls, Bulk Biceps does this between training sessions. Fluttershy seems to think it's cute.
