When anyone, generally a person with "Kezzygal" type qualities, has what is called a Kezzygal Party, they're basically eating a delicious food item (namely chips, popcorn, chocolate, other junk food), all by themself, whilst staring at the computer like a zombie, mostly looking at Harry Potter fanart or their Twitter account. It sometimes consists of the insistent blasting of Alternative, Pop/punk, or Screamo music, usually the bands Fighting For Ithaca, All Time Low, or Mindless Self Indulgence. Try it, it's fun.

Alex: Oh, cool, who's invited?
Sally: Just me. It's a Kezzygal party, duh!
Alex: I'll Urban Dictionary that tonight.
