"Class" with a capital "K"　"slip five"

it`s Veronica Mars again.

What does "Class" with a capital "K" and "roofied" mean? i guess it refers to some kind of drug.

script goes...
VERONICA: How's it hangin', Tad? Let me guess: uncomfortable?
TAD: I guess you and Carmen got those bikers to put me up here.
VERONICA: I had nothing to do with putting you up here. But [reaches into her back pocket and pulls out her knife] I might be convinced to help you get down.
TAD: What do you want from me, bitch? You destroyed my life. You took away the only person that I ever loved.
VERONICA: I don't recall forcing you to send that video.
TAD: No, she did. She left me.
VERONICA: And what good did sending it do?
TAD: Who's gonna wanna touch her now? You know, if I can't have her, no one can.
VERONICA: You are so lucky she has a better soul than I do because I would have taken you down with me.
TAD: So what are you gonna cut me down if I apologise, is that it?
VERONICA: Nope. [Getting up on the plinth] I just want a simple answer to a simple question. Who gave you the rohypnol the night of Shelly Pomeroy's party. Yeah, I know. You roofied your girlfriend. "Class" with a capital "K".
TAD: I-I don't remember.
VERONICA: In about five minutes, people are gonna start showing up for school and unless you want your [points with her knife hand at his genitals] little business to be the first thing they see, you're gonna tell me who gave you the roofies.
TAD: There weren't any roofies. It was GHB. It was Logan Echolls. He gave it to


and also i`d like to know the meaning of ”Slip five" . Thanks.

'roofies' is the street name for rohypnol.
To say to a person that they have 'class' or 'charisma' with a capital C, or 'style' with a capital S, is to emphasize just how Stylish, full of Class or Charisma they are. Note also, "He's trouble with a capital T", which is not a compliment!

'class' is spelt with a 'c'. So, if you tell someone they have 'class with a capital K', you are actually saying the opposite - they don't have Class. It's like Klass is some Frankenstein's monster of a distortion of the word 'class' - and so is their style and manner compared to people who really do have Class!
