2. A girl who will gladly take your heart and then stab you in the back/stomp on your balls, usually by getting off with another bloke. E.g. 'She scuttled on you' or 'you were a victim of a scuttler'
What happened to your girlfriend dude?
Oh, she scuttled on me.
I can't believe she scuttled!
Watch out for the dirty scuttlers tonight
