Horny Gerbil

Having a woman inhale helium right before orgasm, so her moans of pleasure are extremely high pitched.

Dude, I convinced my wife to do the horny gerbil last night... shit was so cash.

remove gerbil from horn

some brass players have a problem with this. Oftentimes, a small mammal is
lodged inside the horn.

French horns, will you please remove
the gerbil from your fucking horn!
