When a host sets out shrimp hors d'oeuvres for a party or special gathering and then subtly puts them away before anyone can eat a single one, due to one of the guests having an allergy to shellfish and not wanting them to feel left out.
"I inquired about the shrimp cocktail platter Alex was setting out, which she told me was one of the appetizers for the party, but shortly after we spoke she quietly put them away before anyone could even see them because of her aunt's shellfish allergy. What a shrimp tease!"
