a crude slag term for bobbing on the knob. ie a blowjob or blow/hand job done while wearing a kilt. you must complete the blowjob with a cum shot to the FACE! (extra points for eye shots)

Once used as just a word for sucking dicks, now has turned into your average replacing of idiot. You will use this word without even thinking of penises or faggotry, only to eventually realize that this is the actual intended use. This word was pioneered and developed in the early days of 2009.
