Eye Bumming 

When a man's eyes linger too long on a ladies bottom, he is said to be 'eye bumming' her.

A lady walks past a man in the street, the man turns to check the ladies bottom out as she passes. The man is then 'eye bumming' the lady, or violating her with his beady eyes, and can legitimately be referred to as a 'eye bummer' from then on. The unfortunate lady has been 'eye bummed'

bumming off 

This might be a very specific geographical location slang term, but it's used in Northern England to mean when a person or people like a thing too much. It's not unlike the saying "...then why don't you marry it?"

My husband is always on his PS4 - he bums off that new COD game.

When did everyone start bumming off Nutella?

"Did you see Uncle Percy the other day?"
"No I didn't. Why do you ask?"
"Well he was down the hospital wasn't he?"
"I didn't know that. What's up with him then?"
"He only had to get his asshole stitched up."
"How come?"
"Well you know Bobby from the Rotary Club?"
"Oh yes. What of him?"
"Well he's not an inconsiderable size in the penis department and they reckon he's loosened up Percy's dirtchute with all the bumming they've been up to."
"Poor old Uncle Percy. "
"Yes, I know. Such a shame. A very nice man."
