Reverski.
By flying FA Off in reverse and turning when you try to boost on them they can effectively force a constant face tank. This means a bigger ship with any level of half reasonable speed can, with minimal skill used, mitigate most of the agility advantages of a smaller ship. It also allows long ranged setups to take advantage of a situation you cannot prevent due to ED's bizarre combat physics, makes aiming fixed weapons considerably easy, and makes it easy to lock pips to 4/0/2.
It's used by some and despised by many, to the point we've discussed changes to flight mechanics in the past to remove the ability to do this.
How you deal with it is up to you. You can master your evasion tanking and bring long range weapons, or do what I do: hit reverse too, wave at them out the window, and use chat to tell 'em where the forward throttle option is.
Perhaps the only reasonable chap to use it was cillit bang, who practically brought it to the surface...in a viper. Rather than forcing a face tank to win against smaller ships, they fought just about anything using reverski and the evasion tanking you could master to win against such builds.
Observe:
It's considered a skill-less way to win by most.
