Let me get some of that,while candy was being passed around at summer camp two anonymous teenagers allegedly over heard a large girl who couldn't wait her turn rudely say "let me get some of that". From then on she was known as LMGSOT. It can also mean anything good or anything bad. But when it is used in a negative context is is used sarcastically.
Wow! that girl is smokin, LMGSOT.
Wow! look how fugly that girl is, LMGSOT!
