a fire deptartment term for a shift, they work every 3rd day. smug little fuckers who think they are better than the other two shifts. They will use any excuse to inflate their heads cause they think the KOOL-AID they drink together makes them super firefighter. They tell how much training they do, but it involves coffee and the price is right.
I'd rather be a cop than an A-shifter.

God made A-shift to give the other 2 shifts a day off

B-shifter to an A-shifter- "so did you guys clean the truck?"

A-shifter- "NO! we where too busy drinking KOOL-AID! and we ran 2 calls so we where way to busy to take time to clean the truck!"

shift means the same as to meet someone. people used to use it all the time,in ireland, back in the day when everyone watched 'den 2' religiously when they came home from school and when they'd spend their evenings with their friends looking for more 10p coins to buy another Mr.Freeze or three. Shifting was innocent, and it was fun! then you became a teenager and shifting had two meanings; you could just meet him or you could go all the way if you wanted to! help revive an old word and bring it back into 21st century conversation by using the word 'shift' NOW!!!! they brought back wispa's so bring back shifting too!!!!!!!!! go on, you know you want to, go out and shift him NOW!!!
