Girl 2: No I'm not. It's just that, ugh I dunno...It's whatever
3- phrase used to avoid a specific topic that one doesn't want to address in order to avoid divulging one's true feelings despite the recipient already knowing how the other feels
Girl 1: Speaking of, have you heard from (insert boy's name here) lately?

Yesterday all definitions of this phrase were put into place. Do I over use the "it's whatever" mantra? Maybe.. Oh well. It's whatever.
