Flex Calves

When you've run for so much that your calves have gotten to the point where you have to wear shorts.

Matthew's calves are so big we could call them flex calves.

Flexisexual

A good definition of this would be someone who doesn't really have only one sexuality, should be used in the ace category because they could be ace with one person and demi with another, romantic orientation is not different if they are this.

"So, last time he dated that person and did do the sideways electric slide. This time he's dating another person and isn't?"
"I think he calls it being flexisexual,"

Pullin a Flexin

To use cheats and exploits to gain a competitive advantage in Counter-Strike:Source during a team tryout.

Ya bro, he dropped a 30-bomb!

Ya probably, what a fag.
