Fav / Favsies

An annoyingly infantile abbreviation of the word 'favorite'. Actual usage:

"I shaved my chest to make me look less like a fifteen year old trying to grow chest hair; my shamelessly-halfbuttoned lavender shirt is my favsies."

Apparently this person got the word from an unofficial Mary Kate Olsen website, which pretty much uses douche-speak exclusively. No surprise there.
