A Niggersec is not a certain amount of time; it is simply four times faster than the amount of time given. For example, if someone did a timed event in 4 seconds, a nigger did this event in one second.
White Man: I just ran the 100 meter sprint in 38.32 seconds.

Usain Bolt: Really dude? I ran the 100 meter sprint in 9.58 Niggersec(s).
