When people play on their phones during Spanish class. If other kids want to call eachother out on it, they
will say "Is that a glowing crotch?" Many people
will find it hilarious and disgusting if you refer to phones this way. Indeed, a spanish
teacher once said "Stop staring at your crotch and smiling, while poking it." They hide the phone under the legs near the crotch, so that teachers can't see it, and its glowing, so it gets the name "Glowing crotch"
