The definition is "Dad they would like to fuck". Seeing that there are alot of sexy single Dads that take care of their kids Females are strongly attracted to them.
When a Dtwlf walks down the street with his kid and no wedding ring all the females in a four mile radius are attracted.

Mostly MILFs and Cougars! (Warning do not try this when in an foreign country or in Canada...Last due to frozen balls.)
