That tingling in your mouth could be a squid trying to mate with you

If you eat a male squid that has not been disemboweled first, you might end up with said squid's spermatophores—basically, sperm-filled packets—attempting to burrow into your soft gum tissue the way they burrow through the flesh of a lady squid. This apparently hurts. We know, because it has happened to more than one person and those cases have been documented in peer-reviewed research journals.
