look up any word, like blumpkin:
 
1.
Love you so much.
You know those coupples who speak in the language of "we" instead of "I", use pet names that make everyone around them sick, and say the L word even though they're only 13?
they're the sort of people liable to use this abriviation in a text, or I.M
guy: night bubs
girl: sweet dreams, snookums!
guy: LUSM!!
girl: I love u more!! xoxoxoxxoxoxoxoxo
other girl: Errr, u guys suck!! "bubs"!
girl 1: Shut up! Just cos ur bf never calls you anything cute!
girl 2: Yeah, and if he did, I'd be sick!
