Blap

Blapping is a way of describing a sudden surge of proficiency in a first-person shooter. It doesn't mean you perform poorly normally, it's just a way of expressing that you are particularly satisfied with your performance. It's most often used shortly into a round after enough time to evaluate whether it's going to be a "good" or "bad" game in terms of your performance. The term derives satirically from rap and hip-hop music where rappers use it as an onomatopoeic representation of gun (usually handgun) blasts. Alternatively, it may derive from being a jackass and yelling it out the window of a moving vehicle trying to scare pedestrians. The need for the word can be partially attributed to the fact that "pew pew" isn't appropriate for conventional, non-energy weapons, and thus an equally expressive sound was needed for firearms.
