incredibreasts 

Rather than normal breasts, refers to breasts of the human female that are so amazing/nice/perfect that you can't quite believe what you're seeing, even when they're right in front of you. They have the ability to cloud the minds of straight men and even awaken the inner bisexuality of "straight" women.

Guy1: Her tits were amazing.
Guy2: Really, how amazing? Details, fool.
Guy1: Impossible to describe man, they were incredibreasts.

Incredibeast 

When something surpasses legendary status; something so awe inspiringly jaw dropping that it will make you shit your pants due to the amount of legendary given off by it's mere presence.

Bob: this sandwich is incredibeast.
Bob: *shits his pants as his jaw drops to the floor in amazenment*
