We were just slacking our time off after the whole exhibition and the conversation just came up with something like this Bro A is somehow related to Bro B due to the fact that they are "同母异父"？This good friend of mine actually took lots of thorough thinking to differentiate between this term "同母异父"？
Another good friend of mine actually lowered it into simple term for her.
Same vagina but two different dick.
