look up any word, like bootylicious:
1. Pad Hands
A serious condition in which drummers who drum exclusively on a gum-rubber pad or any other type of drum pad (i.e. HQ ReelFeel) cannot execute what they can play on a pad correctly onto an actual drum. Causes major embarassment when you want to show off to your friends what you can play on your drum pad, but can't play it on an instrument.
Derek: Johnny's been playing flam 5's on his ReelFeel pad but when I told him to play it on my marching snare, he failed miserably.

Jim: Sounds like Johnny's got a bad case of pad hands.

Johnny: Fuc* you guys
2. Pad Hands
In drum corps, pad hands are the inability to hit a rimshot; a product of playing on a rimless practice pad.
Dude 1: "Man, I just got cut from the BlueCoats..."
Dude 2: "What happened man? You miss those rimshots again?:
Dude 1: "Yeah, me and my damn pad hands."
3. Kaoss Pad
A piece of electronic musical equipment used by musicians to create a limited variety of bleeps and basic drum patterns.

It's first entry into popular culture was its appearance on Muse singer Matt Bellamy's guitar.

However, the Kaoss Pad has now become a symbol for spoilt rich kids who got a guitar for christmas and "want to sound like Muse". Some even spend vast amount of money actually installing the pad into their guitar at a custom guitar shop.

Later, they realise that it's use as a musical instrument is in fact incredibly limited and will discard it after several days of fiddling with "that Supermassive Black Hole noise" the pad can make.
Spoilt rich kid- hey, I just got a learner guitar for Christmas and can only play Wonderwall on it. Ah well, I'll just go out and buy a £200 Kaoss Pad, that'll make me just sound like Matt Bellamy from Muse!

Friend- But surely you want to learn guitar properly first and then build your own original guitar sound and style before spending £200 on a piece of shoddily made metal.

Spoilt rich kid- NOOOOOOOO! MUUUUUUUUUUUUSE! *growls* supermassive black hoooooooooooooooole!
4. Drum Hangover
When you play drums to the point when you can't play one note without your massive headache throbbing. And then the next morning even playing on your pad or tapping on your leg hurts.
Dude i practice paradiddles for 4 hours yesterday! I got a massive drum hangover stop tapping!
5. Umpad
A padding sentence used as a replacement for 'Um'.
Light Umpads include: "Yeah" and "Well"
Medium Umpads include: "Yeah, Well" and "Now, the thing is"
Hefty Umpads include: "Well now, look here, the thing is"
And for the extreme padding, when you have no idea what you want to say: "Well now, look here would you, you see the thing is"

Umpads are a sure fire protection from the ineloquency of 'Ums' and are sure to protect you from criticism.
Reporter: "And exactly what is the proposed law?"
Politician: "Well now, look here would you, you see the thing is; the law is still currently in progress and I'm unable to give a thorough description as to its overall repercussions."
Cameraman: "Nice fucking umpadding."
6. Whacking plastic
Verb. When a novice or inebriated person attempts to play the drum kit for the video game Rock Band or Guitar Hero, but misses the drum pad entirely and hits only plastic.
Whoa, you were really whacking plastic there!
