Steamroller

Horses used to pull road-rollers, but the steamroller arrived with the invention of the steam engine.

The steamroller can only move slowly.

Well, I'm a steamroller, babe / I'm bound to roll all over you

It's more about him testing his wares. He rolls joints. He doesn't own a bong, hookah, smoking pipe, chillum, vaporizer, scale, dugout system, grinder, or steamroller.
