|1.||Single mom discount|
The single mom discount is when a single mother (preferably a MILF) doesn't want to pay full price for something so she seduces the man/women into sexual activity to cover the price.
Plumber: "Alright, ma'am your sink is all fixed, that will be $189"
Single mom: "Oh my, that's a little high, can I have the single mom discount?"
Plumber: "The what?"
Single mom: *Starts to stroke plumbers cock*
Plumber: "Ohh yeaa that feels nice"
...The Single mom and the plumber engage in sexual activity for about an hour...
Plumber: *Putting his clothes back on* "Well ma'am, your grand total comes to $15"
Single mom: "Now that sounds reasonable!"
