More commonly, somebody who goes on Urban Dictionary and creates a definition for the guy/girl that they like/love/stalk in hopes that the person who is defined will see it (tip: they won't) and give them oral pleasure.
May also refer to somebody who gets "butthurt" often.
Homosexuals are commonly offended by this term, thus confirming their status as "faggot."
