Sniff My Bung. Short for Sniff My Bunghole.
The little guy told the bully to S.M.B. This left the bully baffled.

An overly-polite sort of girl that uses phrases like "Tee-hee" and "'Scuse me!" all the time. Used to describe a person that acts like a goody-two-shoes.

Originated from the initals for "Samantha Marie Barnes", who is a girl that acts this way. The infamous "SMB Poem" catalogues her trials and tribulations.
My name is little SMB
My favourite saying is "scuse me"
I love Georgene and Lady Barnes
Even if M Jamba has big man arms

Mrs. Hunter spanks me in gym class
And Mrs. Olscheski loves my ass
I haven't done my homework,
Not for a while
That's why Mrs. Ullman has
Georgene on speed dial!

Thank you and 'scuse me. Tee hee!
