That thing your mom does when she's driving, you're in the passenger seat, and she comes to a hard stop, so she puts her hand out to stop you from moving forward.

Can also be done outside of a car, if one intends to stop another person from moving forward for whatever reason.
Bro, why'd you mom me?

You were about to walk in front of that car, bro.

Oh. Thanks for momming me, bro.
