What is ODOL?

Ontzettend dikke ochtend lul.

Dutch for: Incredible big 'in the morning' cock.

The cause of an Odol is unknown, there are different theories.

It can be caused when a guy has too much urine in his bladder, and so the cock gets in 'erection mode' so the urine can't flow through the cock, prevents a guy from pee-ing in his bed.
