Heating Up/On Fire

A rule in beer pong which states that if a player makes three cups in a row without missing, he/she may continue shooting on his/her turn until he/she misses. Although house rules vary, the player may have to call when he/she is heating up. Upon successfully making two cups, the player would have to call "Heating up," and after the third consecutive cup, the player would have to call, "On fire."

"Are we playing the heating up/on fire rule?"

hexting 

Leaving text messages hoping something bad happens to someone, like a hex or a curse.

Mike's ex girl has been hexting him for weeks hoping he'll get some sort of incurable tumor. I'm guessing she hasn't gotten over finding him in bed with her mother.
