all that the greatest band, brokencyde does. To boince is to carry swagger and wear a dope scarf with a range rover or a luxury sedan in the back. Also you must wear emo clothes, and have skunk style hair with multi colours.

"dude last night at the bar i was boincing so hard, that the dj gave me a shout out",

"yo look at that freaxxxx boincing hard!, all he does is boince"

Boink Buddy 

Someone who has no interest in going further in a relationship with someone, but still integrates sex in the mix.

Similar to the term "Fuck Buddies", but a much less harsher connotation.

I'm not currently tied down, but I do have several boink buddy(s).

Oingo Boingo 

The best band in the universe, fronted by Danny Elfman. Danny Elfman is basically the mortal equivalent of Jesus Christ, only with more chops.

I must repent for my sins and be saved, let me play some Oingo Boingo records.

boing yoing 

The chewy gristle in a meat product.It bounces and boings in your mouth making your steak, chicken or other meat quite undesirable to eat.

That hamburger would have been good, but there were way too many boing yoings in it!
