The Drive-By-Wank (DBW) was first seen in Shoreditch in 2002 and has slowly been gaining a reputation as the ultimate dare!!
The DBW is notoriously difficult to pull off due to many variables but in essence one is required to find a woman with a low-cut top on or a backless top, either way exposing a good amount of flesh.
The DBW'er is required to get himself ready by fiddling with himself so he's just on the brink of shooting his load (extremely difficult to even get to this stage in a crowded bar without getting arrested!). He then blatently runs past her wanking madly and shooting his flith paste all over her exposed flesh and then legging it before he gets lynched!!
