1. certainly posting lots of shit on facebook.
2. Also in Call of Duty
when one decides to show off a bit by shooting through a wall or several walls with eg. a 50 calibre to kill a player on the receiving end.
Also very useful for cover, surprise and...montages.
Maybe seen as a noob thing, I don't know.
3. Illegal in most if not all countries involving a wall.
1. wall is covered in videos. What an A-R-S-E-H-O-L-E who the hell is he/she?
Shiiit I just got wall raped
*Ten year old kid screams and says a highly creative combination of words praising player for kill*
