This is term that labels a males penis. It was created with the belief that sex cures the occassional headache or illness of both sexes. It combines the idea that the penis is also known as meat or stick in a males pants. In addition, sex is the miracle act of cureing minor health problems such as headaches, stress, blue-balls, and many other illnesses that can be cured by a great session of sex.
Last night my women was bitching about her headache, so I gave her a dose of medicated meatstick and PRESTO! she was cured!
This word is quite often used as a female form of Metalhead (although metalhead's can be female)
A true metalchick dresses in a similar way to a male metalhead. I.e - tight, faded jeans, band t-shirts(usually in skinny fit) some piercings or tattoos, and some jewelery. This type of Metalchick tends to dig Metallica, Machine Head, Slayer.....etc.
Some Metalchicks may dress more like girls are 'supposed' to. I.e - very tight pants(usually leather or pvc) tight/revealing tops, and big fluffy hair. This look is favoured by girls who like bands like Motley Crue, Kiss and Van Halen.
JAMES: "Dude, check out that metalchick!"
CHRIS: "She's hardcore man"
Or
JOSH: "Dude, check out that metalchick"
ROBERT: "Man, she looks like the lead singer from Motley Crue, I wanna fuck her"
When a Male is done having sex with a Female partner, he avoids washing his dick for a long period of time. During which time he masturbates, marinating his cock with the juices from the vagina.
This chick I fucked last week was so hot, I marinaded my meatstick so I would not lose her sent.
Mike made a Meatstick Marinade after fucking a hot chick. He knew it would be some time before he would get laid again.
