Refers to beer pong. The cup closet to you on the opponents team is referred to as "han solo" If you call Han Solo and make it into a cup other than the one closest to you and in front, it doesn't count.
Person on team 1-"Hey I call Han Solo"
*makes it into back cup*
Person on team 2-"I think you meant Han NOlo"
Hoe Ass Nigga...That one solo dude in your crew who will fuck your girl either while you guys are fighting or right after you 2 break up.
Be careful of what you say to ya homie about you and your girl my nigga because that Han Solo ass nigga will fuck your girl the 1st opportunity he gets.
When you have to drop a duecereal bad, and it comes out in one large clean turd and only takes one wipe of the crack. One turd and one wipe, hence han solo.
