basicaly it means ohh my KNICKERS

preferebly you should shout the knickers part as loud as you can to upset passing by people over the age of 30
(two girls talkin in the middle of the town)

last night me and brad had a few of his mates over for a rainbow party

OMK, why would you degrade yourself in that way, i would much rather have my boyfriend ninja me.
