Selling Buicks 

to vomit; so named because of the way tbuick can be made to sound like a vomit noise

After drinking 12 beers, Haizle was selling buicks all night long.

selling bricks 

this kinda means selling drugs to dudes. it really just means dealing drugs on the streets, like some upcoming rappers, before they entered the rap game they were selling drugs on the cold streets, this slang is mostly used before the get go, before they start making cash from their rap gigs.

I been selling bricks since elementary, I been making quick money before the rap shit become an option.
my daddy died but before that he was selling bricks on streets of the A, i really admired his perseverance it inspired me to rap actually
my friend got arrested for selling bricks
me and my momma been selling bricks ever since
