Get the Sejokeret mug.
a joke that someone tells that also reveals a secret, whether it be their own, or somebody else's.
chelsea: omg nathan asked me to prom last period!! he's so disgusting!
luna: damn, so close!! all we needed was for it to be bryan instead of nathan hahaha!
everyone else in the group: what?? do you like bryan or something???
chelsea: wtf luna?! i didn't tell anybody else about my crush on bryan except you!!
luna: oops! i didn't know i was the only one who knew, sorry!! but you have to admit, that was a pretty funny sejokeret.
