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?"

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.
