Similar to the terms "you 're the sh**", "you da shizzle" or "we cool dawg".
About as scatological as the original phrase but cleaning it up for those who rarely swear, if at all.

Generally reserved for some/anyone who's helped in a big way or has done something cool for one or a bunch of people.

Meaning: "you're too cool" or a similar phrase relating to coolness.
