Mommate 

A roommate who acts like your mom by tucking you into bed when you're drunk, making you dinner, bringing you medicine when you're sick, and of course picking you up and dropping you off at parties, friend's houses, school, etc.

Becki is the biggest mommate because she had to remind Jess to frequently apply sunscreen in Cuba.

Leah had to tuck Chantelle into bed when she was too drunk to manage on her own. What a nice mommate!

Jess, being the mommate that she is, drove Chantelle, Leah, and Amanda to the bar and told them to have a safe night.
