A health and welfare phone call between friends, flat mates, or relatives, named for Bubbe (Yiddish word for grandmother), that is a play on the term booty call.
1. Have fun on your booty call tonight, but send me a text when you're back home. If I don't hear from you by noon tomorrow, I'm giving you a Bubbe call! Gotta make sure you're not dead in a ditch on the side of the road!
2. This is your 12 noon Bubbe call. Since you answered, I'll assume you're not dead in a ditch on the side of the road, yes?
3. I just saw your tweet that you're home sick today. This is a Bubbe call; do you need me to bring over some soup for you?
