Velcro strap

Velcro strap. Best used to describe a persons stupidity. A stupidity so great that you question their ability to get up and tie their shoes in a morning. They only logical answer is that this person has Velcro shoes in order to stop them spending their life scratching their heads.

He can't be that stupid, surely?
Seriously mate, Johns definitely a Velcro strap kinda guy.
