Top Definition
The phenomenon that occurs when you suddenly perceive your previously mediocre looking boy/girlfriend as extremely attractive simply because other people are hitting on them. This phenomenon often occurs in nightclubs or discotheques.
Stacey looked alright last night at Marquee. But the nightclub effect changed my perception of her. I found myself having to deflect guy after guy who came up to flirt with her!
