From what movie is this scene?
 

A coworker and I are both braindead old men and can't remember what movie this scene came from.

The protagonist needs help from a hacker buddy who lives in his mom's basement. The hacker is surrounded by tech gear and if I remember correctly, is playing a shooter game online.

He tells the protagonist he can help, and gets on the phone. About that time his mom says something to him down the stairs, and the hacker yells, "Mom, I'm on the phone!"

As hero leaves the hacker is back into his shooter, talking to the screen, "Oh, you're dead now...."

I know, I'm an idiot, but I'll take OOT's derision to get this answered.

BTW, this came about because we have a rep from a telecom vendor whom we are almost certain lives in his mom's basement. We refer to the guy as, "Mom, I'm on the phone!"

I think you're thinking of The Score.

From IMDB:

Steven's Mother: Steven, who are you talking to at this hour?
Steven: [covering the phone] I am having a civil [censored] conversation with one of my friends, Mother!
Steven's Mother: [calling from upstairs] Steven, want some lunch?
Steven: [throwing an empty soda can at the stairs] I'm on the phone, bitch!

Bingo! Thanks Duke.

Took me a couple days to realize that OOT could answer this for me in four minutes.
