When I was 17 my gf at the time and me, and another couple, took our single friend to ride roller coasters for his bday. For one of the big rides the other couple said they would skip it because it was too scary for the gf. So me and my gf and bday boy wait in line and ride the thing. It was a monster but we love those.

Other couple is waiting by the exits for us. I think I was saying something like "now that's a fun ride for a birthday" and the girl who skipped the ride with her bf says "oh yeah" and gives bday boy a quick kiss on the lips and says "Happy Birthday!"

My guy is dumbfounded for a sec because he's never had a girlfriend yet. Then he licks his lips and makes a face. Wipes his mouth with his had and says "what the fuck did you just eat?" to the girl and her boyfriend busts out laughing. Like big can't talk for a sec belly laughs.

"Sorry bro! We had some fun behind those trees and uh I think you just ate my jizz. Happy Birthday!"

It had to mean something...
