look up any word, like bangarang:
 
2.
Reptile/serpentish monster from the PC game Starcraft. Costs 75 minerals and 25 gas; has a ranged attack instead of a melee, and can shoot ground as well as air targets. Sort of like an upgraded marine, and is useful when used in conjuction with Zerglings.

Does 10 damage, can evolve into a Lurker in Starcraft: Brood War.

Noob: Dude, wtf? I didn't keep my eye on my Zerg enemy while I was teching towards corsairs, then he comes out of nowhere with 20 hydras and raped my ass. Goddamn hydralisks.
Me:Hydralisks are so useful and versatile. Oh and lolol pwned.

How does it shoot spines? I mean, acid spit makes more sense. Do they grow them back or something?
