Old Dutch 

A group sexual move originally developed by three Dutch-Canadian engineers in the 1980's, and named after a brand of potato chips popular in Canada. To preform it, a couple (the original couple was straight, but it is also performed by gay men) proceeds to have anal sex in the reverse cowgirl position, and the third participant (always a female), squirts vaginal fluid onto both of them.

The man or woman receiving anal sex then would defaecate on the woman that excreted the fluid, and then all three participants slam their genitals (or breasts for women) onto each other.

It remains a popular sexual past-time among Canadian engineering students.

Spencer's such a pimp, he picked up two sluts from our math class and made them do an old dutch. He really reeks today though.

Old Fashioned Dutch Baby 

When one person squats over another person's face and defecates (takes a dump) on their forehead. This often occurs during a sexual encounter, but it does not have to.

I gave Janice an Old Fashioned Dutch Baby last night.

Old Dutchman 

Going down on someone with a mouth full of potato chips (preferably the Old Dutch brand from Canada).

When I give my girlfriend ye Old Dutchman I eat Rip-L chips for her pleasure, but if she's been naughty I munch down on Mexican Chili flavour!
