little no-life weasely loser who amounts to nothing.

Noun: a friend who is usually only called upon by a friend when a more primary/prominent friend is unavailable.

Taken from the term “second string” in an athletic competition situation. In football, if the star quarterback gets injured during a play, the second string is called off the bench to replace him/her. A “Second String Friend” is essentially benched until needed, if ever.

Synonyms: Plan B, Second Choice, Secondary Friend, Benched Until Needed

An insolent or insignificant person; a peon; a nobody.

A pissant is described by Kurt Vonnegut in his novel, Cat's Cradle, as follows:
"A pissant is somebody who thinks he's so damn smart, he can never keep his mouth shut. No matter what anybody says, he's got to argue with it. You say why you like something, and, by God, he'll tell you why you're wrong to like it. A pissant does his best to make you feel like a boob all the time. No matter what you say, he knows better."

1. An insignificant or mediocre person.

2. A tiny black ant, sometimes called a 'sugar ant.' It is called this because this type of ant is a favorite target in urinals.

Little person with big attitude

A person who existentially resembles a speck of dry shit hanging from an ass hair of a gorilla. esp. when said person realizes this fact and sharply hones it's "skill" (i.e. propensity) in the execution of self-serving, smarmy, meaningless, petty vendettas for short term gain, which all results in a net tally of gains which equals to zero. Not even gaining an ego boost, when you consider that their devolved impersonation of an ego is not of enough value to apply. Their biggest asset, if not their only one, tends to be their "skill" (i.e. propensity) to cheat. They are metaphorically refered to as ants due to their common abundance, and refered to as being urinated on ("piss-") due to their general insignificance and lack of impact.
