Antisemitic dog whistle used by Nazi white supremacists. The full story is that the people of diverse origin interned at concentration camps slept in wooden bunks, "boonks". Prebunking is the dog whistle for the events that lead to the rise of the Nazi regime and to the boonks.
Refers to the act of getting buckled before you go out. However one who gets prebuckled not only gets drunk early, but often before his buddies come over for the predrink. This results in extreme buckleling and subsequent possiblity of: Passing out, shitting ones self, sleeping withfat chicks, getting crapped on.
