Texting Sherpa

A person who helps guide you so you don't bump into anything or anyone while you look down and text.

Hey, I need to get back to Scott. Do you mind being my texting sherpa as we head to the car?

bitch honk

The "on the road" version of a bitch slap, done to an offending driver, by vigorously honking the horn.

That guy better not try to cut me off or else I'll have to bitch honk him!
