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.

This word is to be used when no other word can be used to describe the cool factor, greatness, or overwhelming emotion of something. However, the something is neither sick, nor nasty. The combination of the words sick and nasty provide a higher connotation of coolness then even the words tight or wicked can provide. It is kind of ghetto.
Dude, your mom cooks some sick-nasty muffins.
That boy is wearing sick-nasty socks.

Word used to relate all awesomeness in this planet and correlate it to Pyke.

So unbelievably awesome it can't be described. The phrase sicknasty is best used in the same sentence the words son and bro.
