brain potato

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.
