To insert your head into a womans anal cavity (rectum) and while up there in the abyss you stick your tongue out and slowly start rotating your body just like a lighthouse.

To spray shit laterally on the vertical walls of a toilet stall. Note: Typically of a diarrhea-like consistency.
Buddy Lou was rushing to pull his pants down so fast as he entered the shitter after first noticing strong pangs of diarrhea, locked the stall door behind him, but 0h n03s he accidentally lighthoused it with a mighty colon blow.

A dance that looks like a lighthouse.
The lighthouse can only be preformed if:
1 The dancer is taller than the people who surround him/her so everyone can see the dance from far away.
2 The head is turned from one side to the other repeatedly.
Look at Kruger, he totally rocked out the Lighthouse!

This phenomenon occurs when one is defecating in an unclean and/or unsafe environment, and does not wish to make physical contact with the toilet seat. As a result, the person performs the squat maneuver. This accomplishes two things: first, the point of exit for the stool is at a considerably higher elevation, resulting in a high entry velocity. Second, as a result of the pivot point being above the feet, the point of exit is further forward in relation to the bowl. This point of release may be so far forward such that there is no (or shallow) water directly above the asshole. If the consistency of the crap is just right, it will land and stick, remaining in an upright position. If the center of mass is directly above the area spanned by the base, the log will be in metastable static equilibrium, and will not fall down. This is commonly known as the lighthouse effect.

Note: the lighthouse is said to have weathered the storm if it remains even after the ensuing flush, such that there is no toilet paper or urine detracting from the natural beauty of the phenomenon.
-Dude, I just left a lighthouse in that bathroom!!

-Nice! Did it weather the storm?

-Yea! Come check it out!

A lighthouse: area that allows light to pass between a woman's legs and her public area- this must be observed while she is standing up with her legs closed together. If a woman has a lighthouse, one would be able to see light coming through this natural space regardless of how close her legs are together. If she's too overweight if flabby the fat closes down the passage of light.
Even though Jane is overweight, she still has a lighthouse.

A lighthouse is when you're lying on your back making sweet love to a black chick and you start to rotate her on that huge shaft of yours with her eyes closed - every time she makes a full revolution on that throbbing thing of yours she opens her eyes and mouth shining the way to ecstacy.

A technique use to smoke weed. First the user takes a bubbler and fills it with water. Then a sweet J is rolled and placed inside the bowl sticking upright like a lighthouse. The user then places even more weed around the J to fill the bowl creating the rocks. The J is smoked and by that time the user cant use a lighter, but one is not needed because the J lights the bowl by itself.
That lighthouse we smoked last night was AMAZING!!!
