We see “go screw yourself”, but if you’re from a place where Jamaican slang dominates, it’s very likely “go suck yourself”.

It’s usually used as an extreme way to tell someone to “f*ck off”, but can escalate badly with the wrong people.
* Stranger beeps at someone in traffic *
*person being beeped at*: “Ay, go suck yourself!”

GSY is just the acronym or used in text.

Abbreviation for "Go suck your own cock!" An exclamation of exasperation, usually uttered when you want to finish a never ending argument. Inviting your nemesis to perform fellatio on himself, which for 99% of males is physically impossible, is a sure way to A) close a conversation, B) add to your nemesis' anger, and C) confuse him, esp. if you are both male, both straight and never demanded that you suck him off in the first place.
