look up any word, like pussy:
 
1.
being grumpy, aloof, silent and unsociable. having a face that says "i'm pissed. and i'm not done yet coz there's just a lot to get pissed with. go away."
i'm an emo kid and sulking is what i do best.

2.
walking around or laying around being all depressed and with no energy to do anything because you're so pissed and depressed that it's as though you're dying but not quite yet
Today just couldn't be any worse, I'll be sulking around the house for the rest of the evening.
