A thing is when 2 people like each other, and they're "seeing each other" and no one else. And if they do shit together no one will be called a slut or anything cause they have a thing... the urge of dating but not official
Guy 1: I have a thing for this girl

Phrase to literally identify anything as a “thing”. Used mainly to state that something unusual is going on and it’s a thing because it’s in reality.
“The woman at cvs just closed the door 25 minutes earlier so I guess that’s a thing
“My boyfriend is actually a woman soooo apparently that a thing “
“Wow that’s a thing?” (Talking about any crazy situation)
“Mom I just got arrested for walking drunk.. I didn’t know that’s a thing”
