A lame joke told by 3rd graders and retarded 6th Graders.

A new product developed by Apple. Improving on the iPod, now one is able to not only listen to music and watch movies, but iCup also allows the user to see through bathroom stalls and doors.

I.C.U.P or in other words "I see you pee."

A cringy joke made by 2nd graders.

Sounds like "I c (see) u (you) pee". Its also a joke used in Elementary school.

Mostly told by elementary school students. The joke is that if someone spells "ICup", they sound like they are confessing to watching someone pee.
I C(See) U(You) Pee.

The most incredible comeback to any argument. Telling your opponent to spell icup will instantly disable all of their bodily functions and render them udderly defeated. It is the key to the understanding of the universe and can destroy anything that dares to spell it.
