The lyrics of the Big Bang in G-Dragon, Guangdong Province, we will get the meaning that you are crazy?

Funkdafied from Da Brat, the first female rapper to win a platinum record in Da Brat. Funkdafied said it was time for Funk to make the decision, emphasizing Funk's position. Funk is a kind of music originated in America, which combines soul music, soul jazz, R& etc. Blend into a new music form, which has a sense of rhythm and is suitable for dancing. Demo of funk music is widely used in hip-hop music.

In the lyrics of BIGBANG, the meaning is somewhat similar to "Boom Shakalaka", a way of boasting by rappers, similar to that we control Funk.

All of the above is my own understanding. If you think it's okay, you can adopt it.
