Haha, thumb shot is when you can't extend the gun to aim on the fish because it's in a hole or too close. You hold the gun below you and back so the thumb pulls the tigger. Dirty because I couldn't aim at all, had to guess where the spear would go!:thumbsup2:
Nice - but I still prefer the dirty Sanchez!:)
