‘Booty’ and ‘butt’ are synonyms.
‘Call’ and ‘dial’ are synonyms.
But, a ‘booty call’ and a ‘butt dial’ are VERY different things.
"butt dial" is to place an unintended call to someone from a mobile phone when the phone is not in use
Responding to a complaint about illegal fishing, a game warden tried to call one of the suspects but the suspect hung up and then butt-dialed the game warden back. "Maybe the game warden didn't see," one of them said to the other as the warden listened in.
"Booty call" on the other hand is a communication (such as a phone call or text message) by which a person arranges a sexual encounter with someone.
Dictionaries having a sense of humor was not on my 2025 bingo card.
