Get the mac n cheesinmug. An improved name for the Flamin' Hot Cheetos snack. As you may guess, they are very cheesy and often quite hot, as evidenced by their orangish-red color. In the process of eating these crunchy bites of spicyness, your hands and/or lips will become quite red despite your best efforts.
