Awkward buffer 

A person who goes along to a social situation to buffer the awkwardness. Used often when you're trying to get to know someone, but certainly not in the "date" sort of way. Works best if the awkward buffer is a friend of both parties.

Bob: I'm going to meet Maria tonight so we can hang out and get to know each other. Could you come with and be an awkward buffer?

Shelly: Sure! I'm good friends with her, I'll help keep the conversation going :)

human buffer 

the perfect guest who is invited to family get-togethers for the sole purpose of buffering the in-laws from the rest of the immediate family.

Hey, let's invite your brother's new girlfriend for Christmas this year. She was the perfect human buffer at Thanksgiving. She laughed at and made all the appropriate comments during the in-laws' nonsensical ramblings and stupid jokes that all the rest of us have heard a thousand times. She rocks!!!

Band Buffer

My band buffer scaffed their teeth on my shaft, so I grabbed the baby powder and smacked a bitch.

The Buffer 

The last big fart right before you have to take a shit. Usually smells worse than the actual shit. Generally this is the last sign that an oncoming shit is inevitable and imminent. A slow, controlled walk to the nearest shitter may be required.

Holy shit dude, I just dumped the buffer!
