When you've gone to the club with all of your mates to pull a bird and it gets to 1:50 (10 minutes before the club shuts) and most of your mates have pulled yet you haven't. You still want to take someone home that night so you hit the dance floor to go and pull any munter or fat bird to satisfy your needs for the night. That female is a Ten To Twoer.
When one girl is being taken from behind by one dude and at the same time his buddy fucks here in the mouth and they highfive at the same time. This all results in an extraodinary resemblance of the London tower bridge. Therefore this girl is being towerbridged.
Wow dude thats a hot chick man
for real we got to towerbridge that ass man.
Yeah we gonna be towerbridging tonight!
