the act of molesting the inside of another person's mouth with your finger.
Emily and Natalie were sitting on the bed when they decided to start feeling one another's teeth with their fingers, which lead to the eventual feeling of the gums and the roofs of their mouths (which is a very sensual and orgasmic experience because of the sensitivity of the roof of a person's mouth.) Next, Emily started to make out with Natalie's finger.

"Emily! You're making out with my finger!"
"Oh! I am!"

This then continued and is called gumming.

Get the Gumming mug.
Over the course of the past few years, people have come to consolidate words in accordance to the green movement, and stricter school rules prohibiting homophobic language. So the words "gay" and "bum" have been combined into the ultimate beat down - "gum".
(inside the school hallway)
Kid: Look at that kid wearing the rainbow shoes, what a "gum"!
(teachers pass by)
Teacher: Yes those shoes do look like a niece piece of gum.
