You seen that Geezer over there mate? He's Hench, but I bet he's a "Sted Head".
Usually seen outside your local boozer on a summers evening, a Sted Head is a fellow with unusually large muscle growth in the upper body.
If spotted in this most favourable of locations he will no doubt be holding a small glass containing fruit juice. His stance and grin will be wide showing confidence.
His legs will be of normal proportions .
Four or five small males will be admiring him and the whole group will be louder than any other group nearby.
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.
Lee: Frank you seen that guy down the gym bruv? he's massive. He told me he's never taken anything all natural, he said.
Frank: He's not fooling anyone with a build like that, Bruv, he had more juice than Tropicana. He's deffo a Stealth stedhead you Muppet. LOL
It is said of the situation where a person has the bad luck to make contact with his testicles against an undefined surface or object, intentioned or not.
Given the nature of the word, it is more appropriate to design cases where the interaction is made with a moving object, for example, a ball.
Although it is extremely painful for the victim, it tends to be considerably funny to people who witness it.
Today in the baseball game the pitcher took a nutshot; the baseball hit him in the nuts.
Man, I just watched the funniest nutshot video ever.
