I'm not from Maryland, but I love Maryland slang. Some of my favorite terms, and what (I think) they mean:

Stole

To get hit in the face.
Ha, she stole you!

Bama

An uncool person.
Look at these triflin' bamas!

Like a mug

We said this back in Louisiana too, but it means "a lot".
It hurt like a mug!

Cised

Stoked.
I'm cised!

Pressed

Eager or impatient/worried.
Don't sweat paying me back today, I'm not pressed

Jone On

To make fun of.
Man, those girls were joning on me!

Carried

To get made fun of successfully.
Haha, you got carried!

Do they use these where you live? Also ADD YOUR OWN!!!
