Free sex. Free of charge, free of commitment, free of emotion. Similar to "friends with benefits", but without the friend part.
"I met this girl at school, and before we had the chance to talk much, we had frex. I don't plan on becoming friends with her..."

Get the frexesmug. an ex who is now your friend. s/he/they can’t really be called a “friend” because you were in a sexual/romantic relationship. it is definitely possible to have great FREXSHIP with a person after dating, but the term “friend” doesn’t cover it. frex explains it all.
