jammi up

to get ready for bed, to put on one's pajamas

Pause the TV while I go jammi up. Why don't you kids go jammi up before your show comes on. It's too late to go out, I'm already jammied up.

jammin it up

Putting on your pajamas

We was gonna go out tonight, but Amy was already jammin it up, so we went to bed.
