Winter Beater 

An older piece of shit vehicle that you use to get through the winter while your nicer vehicle is in storage protected from the elements of snow and salt

Or

A girl that you date during the cold winter months, giving you something to fuck while everyone else is staying in, but you drop come summer when all the partying starts back up again.

As summer came to an end and the weather began to get cold Jeff began looking for a winter beater to get him through the up coming months
