I listen to a lot of rap and it's clear that they all love doing the same things or are bullshitters. Anyway...
Throwing money in the air at a club (Making it rain)
Going hard in the paint
Drinking non white liqueur (they also like to let you know that people have accused them of being racist for not drinking white liqueur)
Getting white boy wasted
Respecting dead rock stars (e.g Lennon and Cobain)
Poppin bottles (one step before getting white boy wasted I'm guessin)
Wearing backpacks for no apparent reason
