What is a wheelie truck?

I will spot something or some person in public and I will tell my children not to give them any attention. That is what they want. They want you to look at them. You know, like people who go out of their way to show you their tattoos.

I’ve seen many things, but trucks that have been modified to look like they are popping a wheelie kinda leaves me befuzzled. I guess they’ve accomplished their goal of getting my attention, well that and the ungodly noises emanating from the exhaust plus all the curse word music that rattles my head via the subwoofer speaker.
