jeer

From earlier gyr, probably from Dutch gieren (“to roar with laughter, laugh loudly”) (related to German gieren (“to gape, snap”)); or from Dutch gekscheren (“to jeer”, literally “to shear the fool”), from gek (“a fool”) (see geck) + scheren (“to shear”) (see shear (verb)). The OED states no verifiable connection to English cheer.
