a large grouping of hard snot or a solid booger extracted from one's nostrils while contemplating any subject.
while answering my girlfriends question about whether or not her sister beulah with the acne problem was attractive i rubbed my nose and discovered a large mass of hardened snot i then proceeded to pull it out, scrape it off in an ashtray and said to my girlfriend, fuck no !!!! stupid. i just yanked a brain potato so large it would pass for your sisters left cheek.

FF: dafuq is that shit?
Officer to rookie: Stay away from him, he's got mashed potato brains.

Get the Mashed Potato Brainsmug. Man, I caught some major mashed potato brains the last time we tripped. I don't think I could deal with that again.
