bus stop buddy

An acquaintance that you have for the sole purpose of text messaging them when you are bored or otherwise free of time. The extent of your relationship typically stays at the level of superficial text message exchanges and rarely (if ever) blossoms into a real world interaction.

(Immediately following a fender bender)
Victim: Didn't you see the red light and the wall of cars in front of you?
(Quickly shuffling to put away their phone)
Defendant: I know...but I just had to check out this cat video that my bus stop buddy sent me . You know its all about priorities in life!
