When you realize you have donesomething so embarrassing
or compromising, your whole body seizes, you squeeze your eyes shut, clench fists and especially clench buttocks and imagine that your sphincter has snapped closed.
1.You are mocking your boss and he walks up behind you unbeknown. You're in buttlock.
2. You have farted noisily in the car after you think everybody has already jumped out at the mall only to realize that your futureBritishfather-in-law is still sitting quietly behind you, that is until he clears his throat. Ahem. Welcome to Buttlock.
While doing a chick, to put your thumbs on each side of her hip, while your 8 fingers reach over, grabbing her ass with such intensity it causes a "buttlock"
West Midlands slang word for rockers, bikers, greasers etc. In the late 1980s it was used by the UK music press to refer to a specific scene centered around the bands Pop Will Eat Itself and Crazyhead. The term never found favour with readers of 'the inkies' (Sounds, Melody Maker and the still extant NME) and was soon dropped. Now often used in predominantly working-class areas of the midlands and the north to mean someone who listens to rock-derived music and/or dresses in a manner that suggests they affiliate themselves with rock music of some kind.
Some grebo passed with Sabbath playing on his stereo.
The Poppies are at no. 17? God, a grebo band in the charts!
They're playing nu-metal now, bloody grebos!
