The type of person who drinks boxed wine all the time, especially straight into the mouth from the box....because wine's fucking classy.

classy as fuck is a phrase to be used sarcastically to make fun of others who think they are classy, and refer to themselves as classy indviduals. getting shitfaced is a non-classy action, just because you are getting hammered off of your mothers wine, does not make you classy. One glass of wine at dinner, is somewhat classy.

For a college/university chick to get very intoxicated. Most likely blackout, or at least have excessive amounts of memory loss. Requires excessive pre-drinking to whichever event is to be attended, and then countless pitchers of beer, boxes of wine, or shots at said event. A good benchmark for determining whether you got Classy as Fuck the night, if you are still classy in the morning, your night was a success. When a Classy Lady takes a younger lady under her wing as a prodigy, this lady will be designated as a C.L.I.T. meaning Classy Lady In Training.

Things that define whether you got Classy as Fuck are: not giving a fuck about anything, dancing on tables/stages/anywhere, team bathroom breaks, shots in hot tubs, keg stands, funnels, etc.
Things that are NOT classy: throwing up (if you remember doing it), kissing really ugly dudes, screaming, crying, being annoying, fighting, etc.
NOTE: Classy Ladies always wear pearls when it is predetermined that they are getting Classy as Fuck; if they accidentally get Classy, its alright if they aren't wearing pearls.
