When you have become so tired of something/someone, that it is making you sick. Something that mothers often say to their misbehaving, ill-mannered children.
Mother: Tony, I am so sick 'n tired of your shit lying all over, that it has made me sick to the point of vomiting in last nights casserole. I just dressed it with ketchup, so fuck you!
Sick Nasty is not merely sick nor just nasty, it exceeds all expectations of awesomeness and creates its own arena of wild. Sick Nasty is pure awesome in its truest form.
A StarCraft phrase created by Tasteless and Artosis to show their nerd love to fellow team mates and friends during tourneys. Also used whenever a sick play is made.
