Some people don't let seeing others having a good time,no matter what they ride and I've seen guy's blow up because mal riders are getting all the waves.The reason most of the time for this is,they are on the wrong gear for the conditions.
I'd say this guy was having a REALLY bad day

maybe in and out of the water,no need to carry on like a sheep's chop,sorry lamb chop

Hope its all sorted and no more aggro,**** surfing's meant to chill you not fire you up!
