A girl who tries to steal your cum in order to have a baby. Dads all around the world should advise their boys that girls WILL steal your cum in order to get child support. This term was introduced by OMGITSFIREFOXX during a FACK BOII FRIDAY STREAM.
Sonja was named cum thief after she "tried to clean up the cum on the sheet." She later had a baby, got child support and lived happily ever after.
