Cover art for Glue Man lyrics by Fugazi

Bag and drag are referring to buying and smoking weed. The sun coming up is the youth of this person where the loneliness could be maintained, but it's not easy, and all he can do is mull over his thoughts since he doesn't have friends. Eventually the sun goes down and the tide comes in. This is his life now where it is darker, and he feels overwhelmed. His home, which is his pipe, is in his hand at the end of the day. It's the only thing that matters to him and is the only thing he can depend on.

Seems like kind of a heavy song if it was about a regular old pothead.
