Flex social

Social flex: flex your muscles for attention

Here is how this social looks to you and to everyone around...

No argument: You flex your muscles proudly! Kadm flexes those muscles... a proper bouncer from the Grunting Boar!

On someone: You show off to Hart, flexing your muscles proudly. Kadm flexes those muscles in a vain attempt to catch your eye. Kadm flexes his muscles in a vain attempt to impress Hart.
