A type of cannabis smoked mostly in the North East of England.
Brown and hard, but goes soft when warmed up in order for the dealer to cut it into different sizes.
Only 2% THC.
Lasts alot longer than skunk.
The best way to smoke it is with a bucket/boosh or a bong but you have to burn the tac off and sprinkle it in the chillum or pipe.
Tac joints make nasty rockies which burn through clothes.
First person: Hey, want a bit of this tac joint?
Second person: No man, I can't be getting rockie holes in this jacket, sort us a boosh though?
First person: 'Kay, but I can't be arsed sprinkling it, you do it.
To commit tactical suicide, oft in FPS games. Tactical suicides result in tactical superiority, whether by positioning the player committing it into a more favorable location, filling up his health, or denying the enemy a kill / attached bonuses.
Capture the Flag: You're on defense, low on health. You can see the incoming enemies half way across the map. Yet, there are no health packs around. TAC and respawn with full health, ready to put up a more efficient defense.
Deathmatch: Score limit is set to 20; the enemy has 19, and has you cornered. A frag, and his victory, is inevitable - unless you TAC.
Guy 1: Holy crap did you see the chin on that guy!? It was freakin enormous! It was as if the chin ate several other weaker chins and assimilated them into itself!
