shiitake shrinker

When in Japan and a females pulls out a large strap on in front of a man and his erection goes away completely (shrinking in size).

Oh man when I was in Japan this girl gave me a shiitake shrinker and I was ready to come home.

boner shrinker

When someone in your group is no fun and tries to ruin the fun for the group.

We were at the strip club and Norman was being such a boner shrinker and wouldn't stop talking about his problems.
