a farthing. Formerly grig.

fun, frolic, a spree. Old Frenchgigue , a jig, a romp.

“In search of lark, or some delicious gig ,The mind delights on, when 'tis in prime twig.”
Randall's Diary, 1820.
“‘No heirs have I,' said mournful Matt;But Tom, still fond of gig ,Cried out, ‘No hairs? don't fret at that,When you can buy a wig.'”
