filling the cereal bowl 

When a man masturbates while laying down and finishes on his own stomach, leaving cum in his belly button, just like filling cereal bowl with milk. Except the milk being semen and the cereal bowl being a belly button.

Filling the Void

2) A comment which has no relevance or does not add substantive value to the conversation.

Is it possible that they were filling the void last night?

Intending to have intercourse later on. From a rather popular Mumsnet thread, "Do you dunk your penis" about post coital clean-up.
