Seriously, the problem your posting about likely means you are younger than I. Do not make mom jokes, it’s disrespectful and ultimately will make you look like a pussy. Just make sure your pupil is staring directly into his/her soul as you says stfu and you’ll be better off. People who are your friends will not hate you for it, and those who are not your friend will respect you a lot more than if you make a mom joke. As you grow in life you’ll notice adults do not make fun of stutters, and younger people do not get in to much trouble for telling someone who makes fun of a stutter to go fuck them self.
