body harmonica

When you go down on a chick vigorously shaking your head side to side like a rabid dog

I play the body harmonica like a toothless homeless man would eat corn on the cob.

When two biological males stand front to front and skotch tape their dicks together. (As supposedly done by Marilyn Manson and Twiggy Ramirez when they wanted one girl to give them both head.)

"Well, there's two of us and one of her... Let's do that dick harmonica then."

Glass harmonica

A musical instrument consisting of a number of glasses partially filled with water. The glasses are filled to different levels, hence the production of different notes when the player rubs their rims with a moistened finger. The sound thus produced has a haunting, otherwordly quality. It is most famously called for in the "Mad Scene" from the opera LUCIA DI LAMMERMOOR by Donizetti, although that part is now usually played by a transverse flute.

Opera fan A: What's your favourite recording of LUCIA?
Opera fan b: The one with Beverly Sills, because it uses the original scoring for glass harmonica.

Gagging Harmonica

The act of nutting on a girl’s tits and then motorboating them immediately after. When the man’s lips meet the woman’s breasts, the resulting sound will be that of a harmonica as the man simultaneously gags on his own beat juice.

Tyrant: Dude I was playing my guitar and harmonica last night. I love jamming, it’s my passion.

The Boss: Bro I was jamming too. I performed a Gagging Harmonica last night. I splooged on my wife’s tits and then proceeded to play “Piano Man” by Billy Joel. I made it about a minute before I started gagging on my Spunk.

Tyrant: Bro we should perform a duet. I love piano man!
