A sheehan is someone who ditches their friends for their girlfriends constantly. This is referred to as sheehaning. Other types of sheehaning include:
Making plans with you friends and cancelling them for your girlfriend.
Ignoring your friends and only speaking to your girlfriend.

The worst sheehan is a sheehan who wont admit he's a sheehan
