m-string
An M-string is a tiny piece of fabric, leather, or plastic that holds your junk in place and slaps your butt cheeks like a cheap slap from a drunk uncle. It’s what Borat wore when he thought he was fancy.
My uncle tried to wear an M-string to the beach and got laughed at by a group of seagulls.
My friend’s M-string fell off during a karaoke battle and he had to sing ‘Bohemian Rhapsody’ in the buff.
My mom said my M-string was ‘too low’ and it’s been a war ever since.
