To put ones nipple into anothers eye! not meant to be sexual, just for a laugh really! The act of noppling was defined during a random game of truth and dare! It doesnt have to be a dare tho, i often do it just for fun! Enjoy!
Daring to poke someone in the eye with a nipple would be the act of noppling!
Shelly, i dare you to Nopple James!
