Heh

No, that isn't slang for a laugh, that is the name of an Egyptian deity.

Heh is the god of infinity and formlessness, usually shown as a crouching man holding out two palm ribs in his hands, each of which terminated with a tadplole and a shen ring. The shen ring is a symbol of infinity. The palm ribs were symbols of the passage of time, in the temples they were notched to record cycles of time. The tadpole hieroglyph represents the number 100,000.

The image of Heh himself was with his arms raised was the hieroglyph for the number one million.
Heh was a member of the Ogdoad of Hermopolis. He and his consort Hauhet together are the aspects of formlessness and endlessness that existed in the universe prior to the Creation. In Hermopolis, he was depicted as a serpent.
