Any man who feels so inadequate about his penis size that he compensates for it by buying ridiculously large shit he doesn't need. This usually involves buying the biggest truck they can, raising it and putting airplane tires on it. Owning 20 or more large guns, talking about being violent or making threats when they are cowardice. And sleeping with big women to feel adequate, because they lack self esteem. They usually tend to hit, disrespect or yell at women. This may be because women won't/can't sit on their tiny dick. They also usually have a shit load of kids because they try to wear XL condoms, thus leading to unwanted kids whom they also beat and yell at.
Anyone with a unnecessary raised truck with huge tires, lots of guns, a huge 7 room house, or a reputation for lying about themselves in general, yet still doesn't have a goddamn woman. This can make them have small penis syndrome.

Term used for people of an envied lifestyle who do not seem to desrve it. Used by jealous little fags with penis size similar to or less than average. This term is always used by the poor, the scrawney, the obese, the ugly, the stupid, the ignorant. Never used by people who respect that the size of theirs is nothing short of monstous- people like that don't need to assume everyone cool is making up for it.
GUY1: That dude has a ferrari.
GUY2: He has small penis syndrome.

Personality syndrome identified by low self esteem in association with a disproportionately small penis. Symptoms include, but are not limited to, the provocation of others in argument in an effort to boost the Small Penis Syndrome (SPS) sufferer's low self esteem. SPS is easily identifiable among owners of monster trucks and forum trolls. SPS sufferers often associate themselves with the American Quarter Horse (AQH) in a paradoxical display of horse penis envy. There is no known cure for SPS, however, ignoring those afflicted with the syndrome will make them go away.
Just ignore the troll. He has Small Penis Syndrome and is just attempting to boost his self esteem by provoking others.

The idea that one has a small penis, meaning that they perform poorly while having sex, and must make extravagant purchases and show off to others to compensate their fragile ego.

Contrary to the terminology and popular definition, not everyone with SPS necessarily believes that they have a small penis. Small Penis Syndrome means that a person has low self-esteem and feels powerless in one aspect of their life or another, so they buy obscenely expensive things to prove their worth to themselves and to those around them.
Hip Dad:

Hip Dad Friend #1:
Mike, you know that you can't afford that car or your country club membership. Why are you buying so much expensive shit?

Hip Dad Friend #2:
Let him have this, he has Small Penis Syndrome. He's just trying to find his self-worth.

A mental health condition that causes severe anxiety over penis size. It can affect men who do not even have a small penis. This syndrome has developed as a result of our society’s damaging, body shaming attitude towards men’s genitals and the concepts about sex that have been influenced by the porn industry.
Small penis syndrome is poorly affecting his body image and his quality of his life.
