look up any word, like rimming:
 
1.
When three men get into a tub and they rub a dub dub on each others nipples. This is a strange variation of the purple nurple and three men in a tub nursery rhyme.
Get everyone together, the hot tub is on. We can have a good ol fashioned Circle Nurple.

Dude, you want to do a Circle Nurple tonight? Not if you are going to be rough again. My nipps hurt for three weeks after the last one!
