fig2
Pronunciation: /fɪg/
informal
noun
(in phrase full fig) verb ( figs, figging, figged)

Origin:
late 17th century (as a verb): variant of obsolete feague 'liven up' (earlier 'whip'); perhaps related to German fegen 'sweep, thrash'; compare with fake1. An early sense of the verb was 'fill the head with nonsense'; later (early 19th century) 'cause (a horse) to be lively and carry its tail well (by applying ginger to its anus)'; hence 'smarten up'
