is an abbreviation for Socially Camouflaged Targeting System. This is a system invented for self-defence in which you move your hands or posture in a socially acceptable way but increasing your advantage for a pre-emptive strike I.e: you raise your hands without adopting an offence stance and then twatting him when you think you've convinced him you're a soft target, and because you had your hands up in a ''oh god i'm scared'' sort of way gives a more false inpression of dominance whilst shortening the time it takes to strike.
Offender: Oi you, gimme your money
You:*hands come up in a surrender pose*
alright mate i don't want an.....
*Whack, and then run*
