A term coined by Strong Bad of Homestar Runner fame meaning an offspring that is awkward, peculiar, or simply unable to fit in.

"Send your cool son off to join the 'On-Point Kings' he'll have to be... jumped in, your fat son off to join the 'Municipality', he'll have to be... pooped in, and ship your stepheaded red-child off to join the Homestarmy. He'll want to be... jumped out."

Stealth stedhead

Stealth stedhead: A person who secretly uses steroids while pretending to be natural. This term applies to fitness influencers, movie stars, sports figures, and everyday people—someone you might even know personally. Often given away by large veins, mood swings, erratic behavior, and a huge, unnatural fast build.
