What kind of tattoos do skinheads have?

It depends on the skinhead. Real skinheads, which came from a mix of the English mod scene and the Jamaican rudeboy style that immigrants brought with them to the UK, isn't racist. The "nazi skinheads" you see on tv are posers who don't know anything about the real skins.

So, real skinheads tend to have tattoos that involve certain symbols common to the scene - a laurel wreath that comes from the Fred Perry logo, a crucified skinhead symbolizing the damage done by the media pushing the idea of skins as racist thugs, national flags, anti-racist logos and drawings, Doc Marten-style boots, skinhead girls, brass knuckles, the logo for the Trojan record label, that kind of thing.

But also, skins will get whatever appeals to them as individuals. Band logos, their childrens' names, sacred hearts, hotrods, pin-ups - just like anyone.
