Bum Grubs

Worms. Intestinal worms.

Look at that dirty little prick over there scratching his arse, he must have Bum Grubs (ass maggot or arse maggot). He laid a turd and it was crawling with Bum Grubs.

Bum Tunnel

The process by which a bum is born. I.e., a man who creates baby mamas or abuses girls and women physically or verbally had to bum tunnel out of the womb into the world.

Future and Nick Cannon and R. Kelly shouldn't have bum tunneled their way into existence.
These little bay boys bum tunnel their way out into into a crib for the rest of their lives.
