Ah yes, there was a 'Thrombo' down at RAF Stanley in the early days - so named as he was considered to be a wandering clot. Also known, due to his profile when wearing a flying suit, as AWF - Avocado With Feet.
Credit has to go to some pongo outfit, who christened the RAF officer attached to them as 'Lobbo' (as in 'lobster'). He thought it was because he was 'a superior form of crab' - whereas actually it was because he had a head full of $hit....
