Beatles song, "Back in the USSR" gets stuck in my head often.

USSR 

Ultra Soft Silicone Ring; used to fit around both penis and testicles (cock ring) or just the penis (cock crown) or testes (ball stretcher), when used around both the ring restricts the flow of blood from the erect penis in order to produce a stronger erection or to maintain an erection for a longer period of time

My metal cock ring keeps slipping off during sex, although it looks cool I need a “USSR”to do some real pounding!

USSR 

big, shitty, yet slightly intimidating country that used to exist to eventually cause the world to die with nuclear holocaust. Would have saved America from stupidity. We were supposed to die like 40 years ago. after 1962 we just sucked cock. Just look around.. no nuclear holocaust = too many people, kids doing drugs, richard nixon.

Fags.

USSR pwn3z everything your face yo momma hoe.

The USSR stands for the United Syrup Sipping Radicals, aka Canadians. While another abbreviation (more commonly known) for the Union of Soviet Socialist Republics, the United Syrup Sipping Radicals is a relatively new "slang" abbreviation used to describe the Canadians.

Person 1: The USSR is eating too much syrup, now there's a shortage!

Person 2: The Union of Soviet Socialist Republics make syrup?

Person 1: No! The United Syrup Sipping Radicals!

Person 2: United Syrup Sipping Radicals?

Person 1: Canadians dude...

Person 2: Oh...
