A move that allows you to flirt on multiple levels at the same time. The move where a guy is going to/from the bathroom wearing only a towel or boxers and charmingly chats up a girl in the morning with a prominent semi, as if he's totally oblivious to what's going on below the belt. She thinks it's morning wood, but takes a peek to see the size and extent. If the girl notices it, giggles, and keeps enjoying the conversation, she's down now that he's simultaneously broached the subject and tempted her with the goods. Best if you are not small of package.
Works best in dorms and hostels, especially when there isn't much time for the hookup to happen. Also, should only really be performed in the morning.
"Dude, I saw how she locked you down at that party. Didn't you guys only meet this morning?"
"Hell yeah. She told me that she thought I was decent, but once she saw my boner, it was only a matter of time before she wanted on, she couldn't stop thinking about what I was packing underneath."
"You pulled off the Goodmorningwood? Wow. It's hard to pull off, but when it works, it just works."
