look up any word, like bae:
 
1.
New York Yankees All-Star Third Baseman Alex Rodriguez (Nickname: A-Rod) on Steroids.
A-Roid goes down on strikes in the clutch once again.

2.
A filthy cheater and scumbag, playing for the New York Yankees. He just admitted to using steroids from 2001-2003, although he still falied in big situations, and he only admitted once the story had already broken.

For the example, I'd like to quote Seth Meyers from SNL's Weekend Update, sometime in February 2009:
"Earlier this week, in an interview with Sports Illustrated, Alex Rodriguez (A-Roid), of the New York Yankees, admitted to taking steroids earlier in his career -- although, Apparently, never in October."

3.
New nickname for baseball-star Alex Rodriguez (A-Rod) based on his recent confession to Sports Illustrated in which he admitted to taking steroids during his 2003 season with the Texas Rangers.
Barry: Yo! Did you hear about A-Rod?!?!?
Jose: You mean A-Roid?
Barry: Yeah, it's such an eye opener! I never saw it coming!
