Samblam is a name only given to Sams of the highest level of epicness. It it is a promotion from a normal old Sam to an epic man who should be treated with the utmost respect.
Samblam: Willy Wilson! Guess what?!
Willy Wilson: What?
Samblam: I just got promoted to Samblam!!!!
Willy Wilson: What!??! No way?!?!
Sam: (passing by) (muttering and with grumbling) Samblams are overrated anyway....
