Strumming the prawn is when you've been on a 3 day bender and you and your mates fancy a kfc on the scagged Sunday evening, then some sted head lad with a fake tan invites you to the disabled toilet and proceeds to ferociously pet your mary (prawn) with greasy chicken fingers.

A Bloomer is someone with a bright outlook on life who is optimistic in nature. Bloomer's frolic in every opportunity to be happy and try to make the most out of life. The opposite of a Bloomer is a Doomer. The term Bloomer originated specifically as a counter to the Doomer on sites especially like 4Chan.
