Root word being tits, not as in female anatomy, rather awesome, cool, dope, or nice. Tittzer, being the next step up, more than "tits," when something is being compared to something already declared to be "tits." (With Tittzest being something ultimate).

meaning more tits when compared to something that is tits
I received a gift from someone, and in excitement of opening it, said "tits."

A second present was handed to me by the same person, same occasion, and with it being better than the first, I said "This is even tittzer"
