When anyone says " Mickey mouse in my club house" , it means there is metaphorically a penis in their vagina . The reason we say Mickey Mouse is because his head resembles a tiny penis ( Mostly because of the ears) .
Joe: *sends picture of thicc anime girl* lol this bitch is thicc as fuuuuuuck.
Mickey: YOU HAVE JUST BEEN BANNED FROM THE MICKEY MOUSE CLUBHOUSE FOR SEXUAL CONTENT!
People say "come inside it's fun inside" in Mickey Mouse Clubhouse probably because they're afraid of saying "c*m inside, we'll get drunk inside" due to kids being to young to ejaculate or drink.
mickey mouse clubhouse means ABSOLUTE CRUD mickey probably lost his purpose in life and decided to yell at innocent kids in his pathetic so called clubhouse. Its like dora the explorer.
