strange language interaction 1

my mom took me to a pizza place to get take home slices
when my mom ordered a pepperoni slice for me i kept saying “peckeroni” over and over
i didn’t know what it meant, in retrospect it was kind of an awesome wordplay
my mom got flustered and stage whispered for me to stop
when i asked what it meant she said “you’ve got one, i don’t”
she later explained better, that pecker meant penis
when watching austin powers they said a bunch of words for penis
when they said pecker i wanted to lean over and say “i understand this now”
