1. Alcoholics who shop excessively and obsessively for alcohol.
2. Shop -a-h"olic" A break-off sect of the Catholic church of whose members shop around for churches holding services. They hold up any service by demanding that the transubstantiation ceremony be repeated over and over until a) ceremonial wine runs out, or b) they, the visiting Shopaholics, pass out.
1. I tried to pick up some liquor at store but some agressive shopaholics had bought out the entire store.
2. As a practicing Shopaholic we end our multi-communions with "Cheers!" rather than "Amen", at least those of us who are still standing do.
