--> MF: Mother Fucker
--> Cool: Yeah, man, that was so cool.
A piece of Simpsons dialogue (from the episode Homerpalooza) embodies this dilemma:
Homer: So, I realized that being with my family is more important
than being cool.
Bart: Dad, what you just said was powerfully uncool.
Homer: You know what the song says: "It's hip to be square".
Lisa: That song is so lame.
Homer: So lame that it's... cool?
Bart+Lisa: No.
Marge: Am I cool, kids?
Bart+Lisa: No.
Marge: Good. I'm glad. And that's what makes me cool, not caring,
right?
Bart+Lisa: No.
Marge: Well, how the hell do you be cool? I feel like we've tried
everything here.
Homer: Wait, Marge. Maybe if you're truly cool, you don't need to
be told you're cool.
Bart: Well, sure you do.
Lisa: How else would you know?

The hash mark, or, pound sign, is used as a comment, as in, to prevent a line in a file from being parsed. It's used in files to create an unparsed area of the document in order for the coder, the writer, to keep notes or to communicate with anyone that might read the file. Anyone can use the pound sign to ammend a file with notes or instructions as well. See an example below
# Set this to no to disable prelinking altogether # or to yes to enable it. Any other value will # make prelink do nothing. # (if you change this from yes to no prelink -ua # will be run next night to undo prelinking) PRELINKING=yes
The # is also seen in the terminal when the root user is logged in. For example:
