Trouser Rouser 

A phrase used when you see a very hot female/ male (depending on if you are gay are straight as a gate) Well anyways back to the def, you start getting an erection and its just getting bigger and bigger and bigger, and all of the sudden you hear a "rip". and you notice that you boxers are ripped from your big ass boner.

"Omg did you see that hot guy... omg i think i have a trouser rouser."
