Tomark is the word describing the relationship between blink-182's guitarist Tom Delonge and blink-182's bassist Mark Hoppus. Tom + Mark = Tomark. Even though Mark and Tom are not openly in a relationship, they are both married, many times when they are together they show a copious amount of affection towards each other which include, hugging, staring into each others eyes, and occasional pecks on the cheek. Many people "believe" that Tomark exists, even though neither Tom or Mark, have owned up to having feelings for each other, or having a more than platonic relationship. They do not deny it though, and they usually say very homoerotic quotes.

A polite term for shoving a lubricated probe into the Earth's hole to release gas.
