The act of kempfing is to pump a girl full of diesel during 5 second intercourse
then to also disperse the diesel upon the girls stomach or chest if possible. People that kempf usually are attracted to "filling up" girls with the first name Kailyn, Shawna, and Faye. Also the only way to be endowed with diesel flowing through your small penis
is to be obsessed with diesel, trucks, or cranes.
Kailyn - Last night got weird I was riding Joe then he went inside me.
Chris - What's weird about that?
Kailyn - Just that black stuff drained out of my vagina and it smelled like diesel.
Chris - That's a classic
case of kempfing.
