This lesson is Part II of a series. "Colloquial" means "casual" as opposed to "formal," and a "contraction" is just the shortening of words. Let's continue discussing some of the ways that words are shortened in casual speech in American English in ways that are not used in formal writing.
So, lemme just show you.

and is used to express casual assent.
