The act of dragging one's naked arse accross a floor using only one's arms to move forward. Much like a dog does when it has worms

The act of a guy flirting with a girl.
The main word of an analogy comparing flirting with Tuna Fishing. Chumming, in tuna fishing, is the act of chopping up fish to throw into the water to attract tuna fish to come eat the bait (chum) and then subconsciously eat a piece of bait with a hook attached to it.

This is then translated to real life when a guy flirts with a girl he is "chumming" by trying to attract the girl to him.

If you have nice bait, or chum, for example it is much easier to catch a tuna.

Some tuna fishermen have nice chum, but have bad hooks, rods or lines.

And vice versa. A master tuna fisherman would be Channing Tatum who has nice chum, hooks, lines, and a nice boat to bring the tuna fish back to port with.
"Graham is chumming so hard right now."

"Yeah dude, but the tuna hes going for is not highgrade tuna - stuff wont sell for alot back in port."

"I was chumming so hard but the tuna just werent biting."

"Ah, shit man, i guess we will to to another party.

(v) the act of sending out a mass text message to members of the opposite sex in the interest of determining your options. Text must be vague enough to apply to large groups but specific enough to elicit a response.

When you remove the bloody tampon of an unsuspecting female and twirl it around before tossing it into a crowd or moving car window.
That was quite a chumming when Leslie was on her period, and I chummed that bus of Japanese tourists at Bonaroo.
