Siamese French-Kiss

When two or more parties touch and rub their buttholes together. This is not only platonic, but extremely heterosexual as well.

Keithan: "I was cuddling in the bed of a Ford F150 with 36 of my closest homies, and we ended up all Siamese French-Kissing."

Daveth: "Dude, I wish I was that straight and platonic with my 36 closest homies."

Siamese Blunt

A crossjoint (two joints sharing a single point of intersection) as made famous by Saul Silver in the movie Pineapple Express.

Lets smoke the siamese blunt first, otherwise it's gonna break when I put it in my pocket.

Siamese boyfriends

Two guys who cannot function separately now that they are in a relationship

"Do you think Kyle would want my extra ticket to the Beyoncé concert?"

"There's just one ticket?"

"Yup."

"He probably would if he wasn't dating Zak. You know how it is with Siamese boyfriends."

siamese twinning

When you are being cock-blocked so hard by a girls friend that she doesn't leave her side the whole entire night.

Guy: Yo, did you get with Emily last night?
Me: No man, she was siamese-twinning with Lily the whole time.

That girl is always siamese twinning with her friend, you never have the chance to make a move.

Siamese Eel

Siamese Eel refers to a rare sex act with a man that has two penises. The 2nd penis can be either natural, as in the popular Reddit post where a man with two functioning penises created an Ask Me Anything, or artificial.

The term was recently popularized in the show Schitt’s Creek where the character, Moira Rose, feared her series of “tasteful nudes” were leaked on the internet. One of the search terms of the photos were Siamese Eel.

Friend 1: I had a Siamese Eel last night
Friend 2: that’s a myth
Friend 1: *shows photo of Siamese Eel*
Friend 2: how did you even get
Friend 1: there’s a video
