I'm telling 

Another way of agreeing to a statement a.k.a. "I'm saying", but usually pronounced with more sass and a bitchy undertone

Derived from Korean-Canadians, street slang used to say "i'm saying" or "you already know"

Shortened version of "I'm telling you"

Anna: Yo, Clara, did you see what Monique was wearing today. She looked like she went to the zoo after shopping at a thrift-shop and got attacked by every feline in that joint
Clara: Yooo, I'm telling man
