undercock

The male genitalia being viewed from an upward looking angle. Similar to the female version of underboob but with a wiener instead. Also referred to as Australian dick.

I knew I was going to have a rough day when I woke up to my roommate giving me some undercock.

Your mom seemed pretty interested in me so I gave her a little Australian dick.
