333
The Gay Train. 333 is like 69 in that the numbers represent human figures performing sexual actions. In this case, each 3 represents a male (with a rectum and a penis).
1: I'd hate to be the man in front in a 333 gay train, no pleasure at all.

2: Actually, that could be the most pleasurable depending on your orientation.
