bro-case

when a muscular guy looks for any opportunity to take off his shirt and showcase himself; often appearing as a douche-bag rather than cool

(me at stoplight): u know, it's only 68 degrees outside I don't think you need to run shirtless...

runner: dude it makes me aerodynamic!

me: yea ok, and I'm sure your six pack abs weren't gonna bro-case themselves, right?
