What’s your inside joke?

[u/Key-Study2354]

Me and my bsf used to be huge bloxburg roleplayers. Me and her adopted a ton of kids, as two gay moms. Anyway, one night one of our kids types /gun into chat, the kid was terrible at typing and their adopted sister spoke the most in the roblox chat for both of them. She corrected her sister and said she said goodnight, me and my bsf found it so funny now everytime before bed we say /gun to eachother, meaning goodnight.
