someone useful that you would not consider a friend but
ultimately keep around and
take advantage of
stemming from the fact that you always want to keep them "close and warm, i.e. in your pocket"
Can be used as a noun or as a verb.
I tried to hotpocket Shelly as a
tutor, but she wouldn't even look at me after I waited til finals to finally talk to her.
Charlie is a good hotpocket, he works at the restaurant and always
hooks up free food.
