Bro-Math 

The ability to instantly add up the weights on a bar-bell or perform any other "In The Gym" calculations almost instantly.

"45, 10 and 5 on each side that's 165lb"(Marcin)

"Dood, you hit 405 for like 3, that means you should probably max out at like 435." That's some real Bro-Math

Bromathy 

This is a form of sympathy which can only be elicited from or received voluntarily from a bro. This sympathy, whether solicited or offered freely is always in connection with you or one of your bros being unwillingly dragged to some "chick event".

While unwillingly sitting in a Kenny G concert because your GF insisted she wanted to go, you text your bros for a little bromathy: "Dudes! I'm being held captive by my GF at a Kenny G Concert (or some random chick flick, or some romance novel signing event) and I think I'm gonna hurl ... I need a little bromathy."
