Def Leppard drum solo 

The act of using one hand to hold your penis and hit someone in the face repeatedly.

My Def Leppard drum solo gave that girl a black eye.

Def Leppard 

Noun: The Best Fucking band ever! 5 guys, 9 arms and unlimited talent.

Just listen to Rock of Ages, Photograph, Animal, or Armageddon It and you will understand Def Leppard.

Def Totes Fo' Sho' 

1. Literally means "definitely, totally, for sure".

2. A completely redundant yet catchy phrase used to enthusiastically say "yes" without using too many extra syllables.

3. A phrase used when you strongly agree with something.

Alex: Hey Robyn, are you going to the concert this weekend? I heard it's gonna be bomb!
Robyn: I am so there! How about you, are you going?
Alex: Yeah, I wouldn't miss it! Jeff and Evan, are you guys going?
Jeff and Evan: Def Totes Fo' Sho'!
