O2Jam 

A rhythm game similar to Beatmania where you can challenge other players online. The score system relies more on how big your combo is rather than the accuracy and it's really fun. Probably has the most abused hold notes and bpm changes ever.

Guy1: i pass Gargoyle EX in O2Jam la
Guy2: I FCed Gargoyle on HX.
Guy1: USE BOT LA!!! GM BAN U AR!!
Guy2: Moron....

oojamaflap 

To oojamaflap (v) is to do damage to a weakling in the hopes of seeing a sign of strength from them. It is different from hazing but indistinguishable from forced non-consensual character building. Coined by YouTube user variablast.

In April of 2010, variablast oojamaflapped oojamaflipper.
