Check my flow 

Check my flow means like "check how I'm doing, check how I look" it's a way in American slang to say "Am I good? "Check my flow" as in "Check out the way I am, how I look, how I'm doing this" to ask if one looks good doing something, looks cool, and doesn't look stupid.

"Hey, check my flow"
Pink in her song "so What" says "check my flow"
