Acronym for "
Hot Ol' Bitch".
An older, usually 35-45 (sometimes older) year old woman still posessing attractive qualities from her youth.
This term only has full effect with gentleman in an age bracket that would allow
said HOB to be the onlooker's mother.
A HOB is a deviation of a
MILF, but a HOB doesn't necessarily have children. Just like "all squares are rectangles but not all rectangles are squares", all MILFs are HOBs, but not every HOB is a
MILF.
