Mad or eccentric:during the night a camel went magnoon and chased round the lines...
I showed him my revolver and told him if they went magnoon again we should shoot.
Over this interesting discovery they fairly went magnoon.
Their language, when a camel went mangoon, was simply shocking.
Origin
Late 19th century: from Egyptian Arabic majnūn 'possessed', a word encountered by British troops during the Siege of Khartoum and subsequently widely used by Australian troops during the First World War.
