*I'm going to...* Originated as a result of the lazy dialect of the citizens of the Northwestern United States. Imunna -- eye-mun-na (spoken quickly)
Imunna go take a nap.

An extreme chat contraction for "I am going to" that takes "I'm gonna" to the next, shortest version.
Then once I've got some experience under my belt, I'munna open my own 4-5star restaurant. :D
