Kaaba

[Donald Trump]

The worlds biggest [mosh pit]. Also a [sacred] place in [Islam].

A square stone building in the center of the Great Mosque at Mecca, the site most holy to Muslims and toward which they must face when praying. It stands on the site of a pre-Islamic shrine said to have been built by Abraham, and a sacred Black Stone is set in its southeastern corner.
