This expression is from Beyonce's "Get me bodied" song:
Skip to the front of the line
Let me fix my hair up 'fore I go inside (hey)
Gotta check these chicks
'cause you know they gone block
When I take these flicks (hey)
Gotta make my rounds
Given eyes to the guys now I think I found him (hey)
Online dictionary gave me a couple of meanings to the word "flick", the most usual is that quick motion we make with the thumb and the middle/index finger followed by the "a fast gesture" definition.
One of the definitions was also "to glance quickly at someone" but all the examples presented for this meaning had another words to make it clear that this is the meaning, for example:
"she flicked a stare at him"
With the word "stare" imposing that meaning. In the song, while the general context may hint to this meaning, the specific line doesn't so I'm wondering what exactly was Beyonce trying to say there.
