-Creeper [cuh-reeee-perrr] noun:
1.) Those people that never seem to get sick of eating the same meal at the same restaurant 1-5 times per week or telling the same story over and over again. Creepers eat alone and painstakingly attempt to flirt with every female employee within their range of vision.
Something managers may want to remind potential candidates prior to hiring: “you will absolutely encounter at least one creeper per shift, either brace yourself or seriously consider another profession”.
