Fuckboy 

Derogatory, said of a male (boy or man) who behaves like a slut and is thus an acceptable masculine synonym; said male is sleeping around frequently, disregarding and/or playing with the emotions of the opposite party just for the sake of adding notches to their bed post.
Not to be confused with manwhore, which is the term for a man who is easy like a whore, the fuckboy's usual target.

I can't believe you slept with a fuckboy like him. You know they're only in it to get laid.

Fuckboy 

A dumbass who flirts with all the girls and doesn't care about their feelings. Claims he gets "all the girls" but really doesn't. Can't even keep a relationship for a week.

He's a fuckboy. That's why no one likes him.

fucknoid 

Alternate to Fuckhead.
Used as an insult to a person or persons.
Having both the qualities of a Fuckead, (or Fucktard) and a hemorrhoid.

The suffix -noid also said to be attributed to the undesirable qualities of the fictitious “Noid” character.
Also in the Law Enforcement community noid or “No I.D.” often is a requisite quality of many lowlifes and miscreants.

Such perversions of the “F-word” are said to have stemmed from overuse of the aforementioned colloquialism and the desire to modify its usage for more specific tasks.

That fellow is a Fucknoid!

Those Fucknoids are ruining my screenplay!

Fuckboy 

A sex toy with a silhouette tree forearm tattoo and looks like he eats cigarettes. Probably good at some type of action sport, like skating or snowboarding, and will "teach you" but suddenly never has time after youve dropped your panties once.

Last night he said I was perfect, but this morning he said he felt like it was too much too soon. He just got out of a relationship four years ago and isnt ready to commit to anything yet. What a fuckboy.

fuckzoid

n. An asshat. One who is so utterly retarded, he isn't worth consideration nor definition. Hence I'm going to stop defining him now. Fucker.

Fuck you, you fucking fuckzoid

Fuckboy 

A guy that just uses girls for sex, makes them think he likes them (which is very unlikely), and generally leaves right after with no intention of forming a relationship of any kind with her.

Don't date him, he just wants sex. He's a total fuckboy, you'll just get hurt.
