"Crackhead Booboo" is the mother of Stan's crack dealer in "A Jones for a Smith". While on a crack high, Stan finds himself curled up with her.
Crackhead Booboo is voiced by Erik Durbin.
Both she and her son are visible at the back of the drug den where Roger and Cookie Buckingham end up in "School Lies".
Crackhead Booboo is one of the vagrants that Roger employs in his improv troupe in "The Sinister Fate!!", only to find out it is one of the former members he managed to fire.
