A person lacking friends and or little to no social interactions. A milder is also someone who is tall and sluggish and have yet to loose their virginity and have had no affectionate interactions with a female. For example, kissing, making out, blow jobs, fingering.....etc. basically a milder is a unsocial, sluggish, tall, virgin with no ambition in life and will go no where in life.
That kid was sitting next to me all year, I didn't even know he went to school here. What a milder.

He's 17 and a virgin with no friends, what a milder.

A milder is a person that has no hope in life and complain about everything but have no solutions. Milders have very low intellect and more than likely been fingered by their parents. Milders love politics but don’t know what it means. Most milders believe Donald trump or Mary Lou are gods. Never try and reason with a gang of milders.
The local Milders got very confused and upset when they lost the election. They didn’t understand that the lowest number of votes lost. They thought the lowest number won.
