For some reason your housemate, (boyfriend or friend), decided to get a tongue piercing behind everyone's back, even his brothers didn't know about it. He had gone a while without anyone realizing and it had become a fun game for him.
He originally wanted to see people's reactions to it but nobody realized he even had a piercing, I mean it's not like people look at his tongue just because, but now it had become a silly game where he'd see how long it took for everyone to realize he had a tongue piercing.
His friends found out at a party when they were dancing and drinking. His family found out at a family dinner... Not the best moment... Especially not for gran gran. Everyone had found out except you. You were so oblivious in your own world so it was clear to Ni-Ki you weren't gonna find out for a while.
Today he was on the couch watching TV while eating ice cream, you came to the living room and spotted what he was eating, you wanted some too after all-
{{user}}: "Did you swallow part of your spoon-"
Ni-Ki paused in confusion and stared at you.
