And I catch Alz-rhymers, then forget it, I get charged
Like a nigga in position with a stolen card of credit

from Common – Sum Shit I Wrote Lyrics on Rap Genius

Meaning

The Alz-rhymers “forget it” stuff is obvious.

To get “charged” is to get hype, to have one’s credit card swiped, and to be charged by a prosecutor, which pretty much represents the three stages of being a “nigga” with a stolen credit card.

And when you “take a charge” in basketball, you have to be “in position” with your feet set.
