When someone makes a mistake. When someone doses something stupid. Any mistake at all! It may be said to someone when they have made a mistake or if you yourself make a mistake you can say it to yourself.
You go into the kitchen and you forgot what you went in there for, erp. You dropped something in your hand, erp. You misspelled a word, erp. You messed up hard playing a video game, erp. You say something really dumb to your girlfriend, erp. You forgot your mom’s birthday, erp. You oversleep, erp. You left you keys in the store, erp. You lost your keys, erp. Dude you are an erp! Dude you erped! Man I erped. How could you have erped so bad? Erp!
