uncle phil

(n.) a formidable fat-roll situated on the back of one's neck, reminiscent of the one that Uncle Phil had on the TV series, Fresh Prince of Bellaire. Easiest to identify when the possessor of the uncle phil has a shaven head or is bald.

I'm not too photogenic in this facebook pic. --No, it's just not very flattering to see your head from behind-what with the uncle phil you have going on and everything.
