A bullet with deep user-made cuts in the tip. The cuts help the dumdum bullet fragment into chunks on impact, causing severe injuries and bleeding on a scale normal bullets would be incapable of. By definition, dumdums are less accurate than regular ammo.

Dumdum bullets are illegal for use in warfare and may be illegal for civilian ownership in the United States.

Also see dum dum.

Apr 27 Word of the Day
A horoscope so bad that it strikes fear into the heart of the reader, rendering them unable take action or make a decision on anything or to even leave the house. This is caused by a paralyzing fear that those actions or decisions may cause the predictions to come true.
After reading "There is a lot of uncertainty around financial transactions and investments right now, and the wrong decision could result in dire consequences" in his daily Horrorscope, Edward climbed back into bed, pulled the sheets over his head and remained there for the rest of the day.

Edward only had enough gas in his car to get to the gas station but was not sure if he had enough money in his account to pay for gas. His cell phone service had been cut off because his payments were in arrears, and since the only way he could be sure he had enough money (to pay for gas) would be to call the bank, he felt it best to hide in bed and hope his horoscope for tomorrow was more positive.
