A woman who's renowned sexual promiscuity instills in a man the need to "double wrap" his penis in two condoms in order to prevent the transmission of likely venereal diseases festering in the woman in question.
Guy One: Dude, you gonna hit that?
Guy Two: Yeah, but she's clearly a double-wrapper. Good thing I have plenty of condoms with me.
A way of wearing a scarf around your neck...put it around your neck, then take one of the halves, and wrap it around your neck again, so that you have 2 layers around your neck, and the scarf hangs down in 2 halves onto your chest. I like to wear my striped scarf double wrapped as part of my "hip-hop punk" look.
Many celebrities like wearing their scarves double-wrapped, but many of them are sad little popstars.
