Military Fun Sponge

A fun sponge in the military is a socially inadequate, humourless & deeply unpopular person who, through a sense of bitter loathing & revenge, sucks all the fun out of everything. Normally calls senior officers ‘sir’ on twitter.

Dude: why don’t we show our human side & engage online?
Military Fun Sponge: all this social media stuff is only a passing fad & has to be boring.
