Cum Guitar

When 3 or more guys cum on a guitar and the last one to do so must play a flawless rendition of Led Zeppelins' "Stairway To Heaven" without missing any notes.

Example 1:
Chris: Hey man what's wrong?
Matt: Lost at cum guitar and it really

sucks

Example 2:

Grant: Hey dude what are you doing later?
Tucker: Me and a couple guys are playing cum guitar if you want to cum.
