look up any word, like pussy:
Sexual position. During a 180, the girl (or the guy) starts by licking the partner's anus and has to finish in a 180 degree motion until she/he reaches the penis. Usually this position includes a rest at the scrotum for extensive licking.
-Oh man! You won't believe what happend to me last night!

-That hot looking chick gave me the 180 after I took a dump!
