When, after a long night a drinking, a guy has intercourse with a girl and she has to stop to run to the bathroom and puke. While bent over the toilet puking the guys comes up from behind, gets on his knees, and starting banging her from behind. The whole time the guy looks around (like a lighthouse) because he knows it is so wrong.
I took that girl home last night and she was so drunk she kept puking in my bathroom. I didn't feel like waiting to finish so I went into the bathroom and gave her a Jacob's Lighthouse.

Get the Jacob's Lighthousemug. A dude who wasn’t on the urban dictionary before this, so he is irrelevant (oh and he needs friends)
