like a part-timer or a full-timer, but one major difference, a free-timer has no job. they have a lot of free time, so they are therefore a free-timer.
kaatisu: so, what do you do during the week?
girl in club: oh, im a free-timer.
short for "random punters". when working in some area of customer service, like a shop, a customer is a random, so when you see many, then they are randoms.
worker A: oh dude, we better look busy, i spy some randoms.
worker B: maannn......that sucks, i wish they would just fuck off, i bloody hate randoms, what the hell are they doing shopping at 8am on sunday morning!?
