when your mam goes down into a rabbit hole and gets stuck. when she gets out she get the rabbit she caught and dips it into concrete. This is so the rabbit is hard. She then uses it as a dildo. Eventualy the concrete will crcack and a rabbit will jump out saying "oh muma mia" and "yowzers what an adventure"
once upon a ime YA MAM got a rabbit and dunked it into concrete so it was hard so its a concrete rabbit then shoved it up her flange. The rabbit came out of the concrete shouting "oh muma mia"
