lagger
A lagger is a driver who leaves so much space between them and the car in front of them, they might as well be driving on a different road.
This lagger left a 10-car gap between him and the car in front of him. I was like, what is he doing?
I was stuck behind this lagger for 20 minutes. He was going 40 mph in a 60 zone.
This lagger thinks he’s being safe, but he’s just being a huge pain in the ass.
