A bro, or brosky, will walk through your front door unbeknownst to you with a twelve pack of rolling rock or corona, at which point you exclaim: "What's crappening?!"
(1)Waking up late, traffic, spilling coffee on your keyboard, getting ridiculous assignments from your boss. These could all be on your list of crappenings OR (2)that wonderful story your mom tells every year at Christmas about how she caught you fingerpainting with feces when you were two.
A crapenis is a crappy penis, as described by another person after starting to hook up. This can mean it is too small, to skinny, too stinky, etc for the person to want to continue hooking up. It usually means the end of the hookup, unless the person hooking up with the crapenis in intoxicated or just really needs some D.
Girl, I went home with that cute guy last night but it turned out he had a crapenis. It was so small I could barely find it! I used my dog as an excuse to get outta there!!!
