carbon buttprint 

1) The amount of carbon molecules used over a lifetime to produce and maintain a person's butt (including those used to produce contributing animal fats and to transport goods);

2) The amount of methane and other greenhouse gases produced by a person's butt over a measurable time period (e.g., a year or decade).

1) Al Gore may have reduced his carbon footprint by purchasing rainforest offsets, but his carbon buttprint remains equivalent to the annual output of a medium-sized Chinese coal-fired electrical generation facility.

2) The average US carbon buttprint is 4.6 times greater than the average buttprint of Zambia, New Guinea, or Ceylon.

"Hardly. Her music is absolute cheeks."

"My boyfriend say LaFlame is cheeks."
"Tell your boyfriend I said it's his mixtape that's cheeks."

Breadhead 

Someone who is addicted to obtaining money and building wealth. A money addict and fanatic. Breadheads often work more than one full-time job, and some even participate in illicit activities to "obtain the bread".

A breadhead is like a crackhead, but for money instead of crack.
