I, unfortunatly found out the hard way what one was. I had grilled pork with stir fried veggies for supper. I was starving and ate too fast. I got the first pains after a few bites, it passed, then stupid me continued to eat fast but smaller bites that I thought I chewed well. It took 45 minutes to get up maybe a tablespoon of meat and lots of slime. It felt like it was stuck in my throat. I tried taking a deep breath and holding it, but I couldn't get a deep enough breath without it hurting. Hopefully I learned to eat slower.
