Usually has 2 or more definitions depending on situations:
1.If it's in real life,it's just a mad man using his gun as often as drops on water in a water fall.
2.If it's in a video game and it's an Esports type,same thing as the first one.
3.If it's in a video game,and it has projectile weapons (For example,TF2),it's outright spamming.
1.Look at that man,he's trigger happy with that M14A1!
2.Oh my god,look at that noob,he's trigger happy.
3.Can someone ban that guy?He's trigger happy.
Most people will say its someone who will shoot anything they see, but there's a whole other definition for it. Trigger Happy can mean someone is happy uncontrollably, they'll see something and they're happiness is triggered.
Person1: *smiling and giggling uncontrollably*
