History Main / PecFlex

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 [[TestosteronePoisoning 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".

* In ''Manga/HowHeavyAreTheDumbbellsYouLift'', Naruzo Machio will do this whenever he hears a word that sounds like a muscle or a pose, flexing so hard that his track suit ''explodes'' off of his body. His {{Bishonen}} head, however, [[TinyHeadedBehemoth remains the same, making him look utterly ridiculous.]]

* In ''Disney/{{Moana}}'', Maui does this at the beginning of his IAmGreatSong. Even better, he flexes each pec one after the other, bouncing his AnimatedTattoo across his chest! "''I know it's a lot, the hair the bod / When you're staring at a demigod!''"

* Happens precisely once in ''Disney/MeetTheRobinsons''.

** Terry vigorously flexes his left pec (nicknamed Eugene) when he is bluffing.

* ''Series/{{BrooklynNineNine}}''. Terry loves this trope!

** He befriended Sig Curtis, Izumi's husband, through a flex-off. It was [[SugarWiki/FunnyMoments bloody hilarious]]. And it was followed by [[SugarWiki/MomentOfAwesome BLOODY AWESOME]]!

* In ''Flim/TheDuff'' Robbie Amell's {{Jerk Jock}} [[{{JerkWithAHeartofGold}} with heart of gold]], Wes, did this in front of Mae Whitman's character, [[{{CoolLoser}} Bianca]] during a confrontation in the boy's locker room.

** At least to this troper, it kinda sounds like the narrator keeps complimenting the guy.

* VideoGame/LeisureSuitLarry can do this after hitting the gym (a lot) in ''VideoGame/LeisureSuitLarry3PassionatePattiInPursuitOfThePulsatingPectorals''. Look at the subtitle, after all.
* VideoGame/{{Undertale}}: Aaron, 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 [[spoiler: engaging in a flex-off with him until he flexes himself right out of the battle screen]].
