The Great Pyramid of Giza 

A sexual act; an extension of the "Eifel Tower", but greater, thus the term "Great Pyramid." Involves the female on all fours giving to the first of four men doggy-style or anal, the second a blowjob and the last two hand-jobs. The four men all hi-five to create a pyramid shape. Also, a transitive verb meaning to partake in the nominal form.

Did you hear that Kelly Eifel towered those two dudes?

You thinks she's a slut? Brenda was in a great pyramid last night with half the baseball team.

The Great Pyramid of Giza 

When anywhere between 10,000 and 100,000 men shit on a girl's chest thus creating one of the 7 wonders of the world.

Has anyone seen Faye, Chrissy or Hillary?

Yeah, Faye just became part of history by having the Great Pyramid of Giza built on her while the others watched. Good thing is that now America has something that's more than 3 years old in it.
