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
