AJ - that hat your wearing is seriously coolio.
BOTH - coolio amigo!
people say that Coolio is a one hit wonder with his chart topping song "gangstas paridise" but that is not true...Coolio has many great songs such as "Geto Hilites" "Sumpin New" "Too Hot" "Fucc Coolio" and "Exercise Yo Game" so his album "Gangsta Paradise" is considered a classic by those who heard songs other than just gangstas paradise
Sarah: coolios, thats awesome!
Mark: you wanna hang out after school tomorrow?
Star wars is so coolio.
