A distance of at least one unit of seating (e.g. a chair, a foot or two on a bench) in between you and at least one other person. It is most often used when: a) a foul odor is emanating from the person next to you b) you don't want to be accused of being too close to a person of the same sex for, well, obvious reasons...homosexuality c) discomfort
"Hey dude you smell like shit, we should have a 1 deskbuffer zone or I'll pass out during class."
The number of people needed in a group so you can enjoy yourself and not have to worry about having too much face time with *THAT* person in your circle (the frenemy, the "let's just be friends" ex, the hookup that turned out to be a really bad idea, the tool, etc)
Damn, Kelly responded to Rob's Taco Tuesday invite too; looks like only four of us. Let me ask Zak and Sara so there's a buffer zone.
The part of an item of food you and a friend purposefully don't eat when sharing said food item, as to not accidentally ingest some of the other other's saliva. Thus preventing the spread of germs.
Mark: "Dude can i share that piece of pizza with you? I'm starving.... "
John: "Sure... I guess, we just have to be sure to leave a saliva buffer zone..."
Refers to the distance between Uranus and the outer perimeter of your butt-cheeks, in terms of how far an accidentally-released blob of poop has to "travel" before it reaches --- and subsequently soils --- your clothing and/or whatever surface that you happen to be presently sitting/lying upon.
Many people think that having a huge flabby behind in undesirable, but it can actually be an advantage if you occasionally suffer from liquid farts, since it provides you with a greater butt buffer-zone; this is especially fortuitous if you happen to be sitting or reclining at the time of said unexpected discharge, since it is exhaustingly more laborious to properly sanitize a seat-cushion or mattress, whereas soiled clothing can usually just be soaked in detergent-solution and then tossed in the washer.
Ruler of Lake Titicaca. Rumored to have a bunghole that gets very angry if it does not receive toilet paper. Cornholio the Great is often seen walking around with his shirt over his head and his hands in the air, chanting songs about his power, and his bunghole.
"I am Cornholio! You do not want to face the wrath of my bunghole, for I need TP!"
Butthead: Shut up, Beavis! (uh huh huh huh)
Beavis: Um, okay. (heh heh heh heh).
