Get the Titty Tag mug.
A game played where a small group of guys individually run behind a girl (preferably wearing a bikini) and pulling her top either up or down, revealing her tits to the other awaiting guys. The one to have pulled down/off the most tops in a certain time period (the time period is decided amongst those who are playing) wins.
Guy 1: *titty tags Jenny*
Guys 2,3,4,5: "BOOBIES!"

The event in which you or the driver next to you is attempting to change lanes, but both vehicles either slow down or speed up which makes the lane change unsuccessful.
