this is a drink (sort of) it's the process of taking a shot of tequila with the salt and lemon.
This is the typical, 'Salt, Tequila, Lemon'. Known as a threesome because they go perfectly together and it's like an alcoholic orgasm in your mouth.

This term is quite well known around the north west.
Girl: Let's have a threesome
Guy: Ok
Girl: You bring the tequila!

Threesome is sex with three people.

A threesome can be consisted off:
Two men and one woman
Two women and one man
Three men
Three women
If sex with three people is a threesome, and sex with four people is a foursome, then I know why everyone calls me handsome

A Squidward Threesome is a BDSM threesome involving two disobediant subs, or brats, and a dom. It involves the brats disobeying the dom’s orders, expecting to be punished, while the dom punishes them for mutual sexual pleasure.
I just had the greatest Squidward Threesome, man. I dominated the fuck out of those two girls.
