My Spydey Sense is Tingling

As any Team Fortress 2 player knows, a Pyro is a Spy's worst enemy. This is due to the inhuman sense of 'spy detection', or 'spydey' for short. The spydey sense – a cloaked spy's nightmare.

The spydey sense: the uncontrollable urge that calls Pyros in Team Fortress 2 to spy check everything, everyone, everywhere. It's that itch you get when the Scout is moving just a bit too slowly, or that Demoman is avoiding you in the hallway, or that Soldier hasn't fired a shot in far too long. It's that urge to keep that flamethrower flaming, because you never know when there's a cloaked spy around. It's that unsettled feeling that you're being watched, which leads to the inevitable course of action: SET EVERYTHING ON FIRE AND SEE IF IT BURNS!!!!!

This meme first appeared in several Youtube videos. It is unknown who first started it, as the pun is rather obvious and practically begging to be made.
