physical contact of a relatively advance nature between two consenting teenagers who are not going out, and probably never will go out, and who are just entertaining each other horizontally and a party or boring movie or something.
That movie was so boring, I ended up scamming with that guynext to me.
Gum used to freshen breath right before a heavy makeout session. See scam. Usually done by high school kids.
Guy1: Yo, I'm going to ditch class to go to a scamming party at Lisas house.
Guy2: Be careful homie, you just ate a bag of Funyuns.
Guy1: It's all good, I brought my scamming gum.
