Amber Rose -- Lots Of People Say Conversate, Stupid!

Amber Rose knows the word "conversate" is not in the dictionary, but everyone needs to chill out. She's teaching her kid a variety of language skills, including common parlance.

Amber is pissed at all the criticism on social media, telling friends she knows "conversate" is slang, but here's the thing -- people speak slang! So she says ... what, people aren't supposed to teach kids words like "fleek," "turnt," etc?

Amber caught flak when she posted a video of her son showing off his impressive vocab ... especially for a 2-year-old.

Sebastian's actually a little brainiac … he can already name the planets and identify types of dinosaurs.

Props to Sebastian ... and Amber.
