What is Greystoke?

Based on the 1984 so-called epic 'Greystoke: The Legend of Tarzan, Lord of the Apes'.

While having an 80's movie marathon, many have found that things come to a screeching hault and all is ruined when this long, dry movie is put into the mix.

Greystoke may be used in place of the f word in many situations where things go terrible wrong.
