Actually it's just really fun and a pretty awesome way to spend time on a really nice day. If you're offended by it, you deserve it for being such a dick about it.
I'd just leave it at fuck-you-very-much-too-sir-have-a-good-day, but I'm actually really confused. What does poi represent to you culturally, and what about that pisses you off? Obviously it's not about the actual act of spinning balls around on the ends of strings because that's just a really dumb thing to object to.
Oh dear, I forgot about that. Sorry.
Well aside from the aforementioned family annihilation, poi and related things are rather synonymous near me with trustafarians who will probably go on about how they found themselves when travelling, or talk endlessly about drugs. Tedious, obnoxious, rich kid arseholes who'll expect you to be impressed by the fact that they can spin some balls around and how good they look with their shirt off (which is obviously unacceptable behaviour unless you're a) playing a gig b) fighting c) both). One of my best mates has become extremely proficient with poi purely so he can humiliate people who're being annoying with them.
Oh yeah, and fuck the guy with the acoustic guitar double hard.
Also, I'm a
really miserable git. And that's why I drink. Speaking of which, I do believe it is booze o'clock so I'm off.
