When trying to describe something so fantastic that the word alone just doesn't cut it. Something so fantastic that it's fantasticness can only be equalled by the awesome power of the female mammary glands also colloquially know as tits. A combination if "tits" and the suffix "tastic". Titstastic.
Duke: Bro, you have to try some of my weed-flavoured cookies I baked this morning, they are fantastic! Nothing can beat them!
Brent: Oh yeah? Wait till you try my pussy-flavoured homemade icecream with a hint of lemony mint!
Duke: Wow! Now that's beyond fantastic! That is indeed titstastic, bro!
