Russian word for a dick head

Visiting Mother Russia, I hear old babushka arguing with two men about the meaning of "zalupa". She say, "No no no! Is tip of cock. Does not count."

Literally, the tip or head of the penis. Figuratively, a dickhead.

Usually russian call a part of a dick as "zalupa". Zalupa is situated on the top of a dick.
