OMG

Rainy day, picking the boys up from school:
Peanut: Mom, why did you park so far away?
Me: Because it's the closest spot that was available when I got here.
Peanut: It was not. There's a spot right there.
Me: There was a car parked in that spot earlier.
Peanut: Well, what about that spot next to the tree? You could have parked there.
Me: There was a car in that spot, too.
Peanut, with a totally awesome valley girl accent: O...M...G...
Me: Seriously? We're doing "OMG" now?
Peanut: What? Mason says it.
Me: OMG.
