the illusion that one is in a perpetual game of simon says, and as a result, will not obey anyone unless the command is preceded by “simon says”
did you hear about thomas’s accident? i heard he has a case of simon syndrome.
Simon Syndrome (also known as Lover Syndrome) is when someone avoids you or gives you the cold shoulder due to a significant other, boyfriend, girlfriend, etc. It also implies to people who hang out with their lover and avoid their own friends.
Friend 1: Ugh, ever since Julia got her boyfriend she's been giving me the cold shoulder and not hanging out with me or any of her other friends.
Friend 2: Oh she definitely has *Simon Syndrome*.
