Essentially, Pumping and Dumping refers to chopping and screwing a dubstep song. Much like Dj-Screw chopped dirty south bangers, pumping and dumping lowers the pitch and tempo of the song, and emphasizes the LFO wobbles. It actually resembles Purple more than dubstep. And there is more chopping, to the point where only the skeletal structure of the song is faintly present. This began Sept 22, 2011 and was created by B-Pride.
Yo! You hear that new Caspa joint!? B-Pride pumped and dumped the shit out of that track, that filthy felon!
When a friend breaks off a friendship with another friend, much like a regular breakup. Usually, the dumpee is unaware of why they are being friend dumped.
Amy: "I don't think we should be friends anymore."
Beth: "Why?"
Amy: "It's just not working out."
When you are completely happy in a relationship and out of nowhere your signifigant other decides s/he isn't. You probably didnt see this coming and it felt as if life had bitch slapped you, its okay though. Go eat some ice cream and cry (meaningless hook ups and/or alcohol are optional but suggested).
Boyfriend: Hey you seem really happy with us.
Girlfriend: Yeah I am, I love you so much!
Boyfriend: ....
Girlfriend: What's wrong?
Boyfriend: I'm confused but I don't feel a connection to you anymore. Sorry but I don't think it would be fair to stay with you.
Girlfriend (thinking*) FUCK. fuck. I need some alcohol because thats what you do after getting dumped.
a situation where your boyfriend/girlfriend doesn't actually break up with you, but they ignore your texts, emails, and calls until you eventually give up the cause.
ashley: i haven't heard from my boyfriend in 5 days!
robin: have you tried to call him?
ashley: yeah, a few times! do you think a dragon destroyed his phone?
robin: no. it sounds like you got ignore dumped.
When you find out you're significant other no longer wants to be with you, after seeing that his/her status on the oh so famous myspace now claims to be 'single', as opposed to 'in a relationship'. Other big clues are when you're removed from their top 8, or they have proceeded to flirt with others in their 'comment' box. God bless Myspace.
