verb, intransitive The act of looking up oneself's first name on urbandictionary in an attempt to produce an ego high by reading the overflow of entries made by other people complementing their boyfriend or girlfriend. Those who exhibit this phenomenon typically have a forever alone relationship status, do not receive complements from family and friends, or, if done in the company of others, are being attention whores.
