When riding an elevator up or down, right before the door opens, you release a massive fart. You then quickly leave the elevator and avoid eye contact or conversation with anyone boarding the elevator as they will soon discover the rude deed you have committed.
Dude I left a knarley tactical insertion for like 10 old people a minute ago.
The act of inserting a straw into two throbbing penis's and then proceed to rub each other off. Who ever makes the other ejaculate is the winner and shall celebrate with the oozing winnings of the other opponents dick milk.
Cock blocking isn't cool man, you owe me a tactical insertion.
