When someone is completely over the top or extra (B. Spears in 2007). The people in life who always are "pissed" or acting out just because they need attention.
Brittney (after a long night of drinking/ being a psycho girlfriend): I can just tell by the way that he is looking at me that he is going to cheat on me.

Lucas: Brittney, you do the most.

when a person does way more than is required from the situation.

The English word for "doing the most" is: "Supererogation" which is defined as; "the act of performing more than is required by duty, obligation, or need"
Dude 1: Did you hear John did today's homework and tomorrow's homework?
Dude 2: Yeah, John is always trying to impress the teacher, so he's always doing the most.

If you want to be fancy
Dude 2: Yes, John tries to impress the teacher, but doing homework which has not be assigned amounts to supererogation.

Trying way too hard to be impressive but only causing self-embarrassment.

Busta Rhymes was DOING THE MOST when he posed in a cell wearing a prison jumpsuit for his "TheSource" magazine picture spread and article.

When someone had been overwhelming, doing a lot, not even in their lane at this point, just trying so hard when it's not needed.
"Did you how fast Jay was jugging that bottle of beer last night ?"

"Yeah, he was doing the most"
