To "butt plug" something into the anus instead of injecting it intravaneously. (Usually junkies do this when their needle breaks.) Boofing or plugging is not as strong as shooting it up, but is stronger than snorting it.
extremely drunk, derived from the boof box of beer from milwaukee, which was a ton of beer at an insanely low price. usually coincides with stumbling and vomitting.
Unexpectedly blindsided/dumped by a (wouldbe)girlfriend. From the word 'bufu', short for butt fuck. If you are a hetero, the last thing you expect would happen or would want to happen.
