little no-life weasely loser who amounts to nothing.

A pick me is a woman that is willing to do anything for male approval. She will embarrass or throw other women under the bus to achieve this goal. The unfortunate thing about a pick me is usually the men they are trying to seek approval from are of poor quality and treat women badly, leaving little real benefit for the pick me.

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.
