Crab Head 

Describing somebody as having pubic hair on their head that has crabs in it, said/meant as a joke, and is mostly said in a ridiculous tone, that usually sounds somewhat Liverpudlian (please take no offense from this).

headcrab 

A small basketball-sized alien found in the assumed fictional game Half-Life.

Headcrabs are small light yellow domes with four legs. Their two front legs are long grasping claws, and the two rear are simply stubs to walk on and jump with. Headcrabs find a human-like host and leap for the head, hence the name. They orient themselves on the head and cover the host's face. Their mouthlike structures somehow take control of their host's brain activities and keep them alive as the headcrab. The "zombie" then conforms over times to include long pointy claws on the hands and a mouth that opens between the ribs.

A fully grown headcrab turns into a gonarch, commonly called Big Momma. Four long armored legs and a circular shell to cover the top, gonarch is radial in symmetry. She has a large eggsack and gives birth to baby headcrabs often. Few headcrabs live to this age.

Headcrab Zombie 

Headcrab Zombies are Zombies from Half-Life and Half-Life 2. In Half-Life, scienctist had been turned into Zombies from the Headcrabs. In Half-Life 2, Zombies are from Citizens, but these Zombies can also throw debris at you. Zombies are usally found in non-combine locations (like Ravenholm).

To kill a Headcrab Zombie, you need to use a .357 Magnum or Shotgun. If you don't have those use your Pistol or SMG. Crowbar is ok with Zombies but you might take some damage. Really you need to aim for the head (where the headcrab is), if you aim for the lower body the Headcrab might survive. Throw debris at Zombies if you want but be careful of the suriving Headcrabs and their Torsos. Headcrab Zombies also come in Torsos. Zombies sometimes have no legs so the torsos crawl around in crouch areas like the Auto-Gun junk yard in HL2: Episode Two.
