cop, meaning steal or general aquire, has been discussed.

one can cop a lipstick, (or from the old song,
"Shine me buttons with Brass-o,
its only tu'pence a tin,
you can cop or buy it at woolworths")

or cop a squat (sit down)

or cop a plea (as part of plea bargain, plead guilty to causing a 'disturbance', and not got to trial for shoplifting)

to cop out it to disown, or disemberse your self of something..

cop to mean steal/aquire is old (almost 300 years as i recall!)
