you mean flanking.....

Your talking about high level players beating up on low level players that have no chance of fighting back whatsoever. If so most players are culprits of ganking.

Gank example, 5 stealth bombers warp in on a hurricane then peace out immediately after.

Another one, hulk is mining in a belt, warp in with a small frig gang, web and point hulk, blow it up. (shout out to hulkageddon)

Not always - we sometimes use lies as well.

so basically you are making "glass canon" loadoouts which focus on DPS

You sure about that?

A bunch of cheaper ships attacking a more expensive ship in high sec knowing that the concord is going to arrive and destroy them has nothing to do with kamikaze or suicide?

Not necessarily... You equip mods that are made to bring down an enemy player, ganking isnt so much a fit as it is choosing how and when to engage a target so the battle ends up favourably for you. If i know a frig is on a gate id send a couple frigs around to the opposite side of that gate to wait for him while sending another two frigs to push him through the gate so the waiting frigs could tackle him while he tried to warp.

A gank fit would consist of a web, a disrupter(point), and some sort of speed
Mod like afterburners or a microwarpdrive, also preferrably tech 2 autocannons or Lasers.

Well like in Dust, you take your scout, load him with Remote Explosives. Run jump on the tank, and plant your remote explosives. Your probably going to get shot down, but you have enough time to detonate. It is basically a kamikaze run.

I've seen people call a militia dropship, and ram it into a myron. It destroyed both ships. Would that count as ganking?

in all seriousness, there is no "ganking" in a game like Dust. This isnt League of Legends. In military games we use military terms like flanking, reconnaissance, ambushing, scouting, patrolling.....etc.

you get the idea.

It's about the context. In EVE at least -

For fitting it's the opposite of Tank - Your ability to absorb and repair damage. Gank - It's your ability to pump out damage.

When you do it to someone you're trying to remove any possible outcome to a fight which doesn't end with them being dead in as brutal a fashion as possible. This can take the form of a large quantity of people behind you or just the right tools (lol jams, tracking disruptors, capacitor warfare) to remove any possibility of a good fight for whoever you are ganking.

I don't think there's a 1:1 correlation in Dust but I'll take it as meaning you try to stack the deck in your favour where at all possible at the start of every engagement. In which case guilty as charged.
