I think when I see a guy driving a big jacked up truck I automatically assume his junk is small.
Why do you assume his junk is small?
I think guys with big trucks are all insecure about themselves.
There is nothing wrong with someone driving a big truck if they like it. It does not necessarily say something about them, it is bad to think that way.
You are such a loser taking their side.
There is no correlation between driving a truck and the size of the junk. It's illogical to think people who drive a big jacked up truck have a small junk. You should talk to such guys, you'll realize not everyone is insecure about themselves.
