Jaco

handsome and fun, he is the guy that starts the party. always looking for the laugh and there when you need a hug. very popular with the girls. kind and open-hearted and loved new places and people. curious and generous, clever and well-mannered he knows how to get what he wants. everyone wants to be around him.
girl: where is jaco? he said he would be here.
girl #2: “here he comes, jaco!!!”
like how a dozen is twelve, and a baker’s dozen is thirteen, a jaco is a length of time lasting for two minutes.
can be multiplied or divided to apply to most lengths of time, eg 10 minutes is 5 jacos, and 30 seconds is a quarter of a jaco.
conversationally, the word jaco can be used instead of other words such as ‘jiffy’ when telling someone that you won’t be long.
sorry, i’ll be with you in a jaco.

the next train is in about three jacos.
a nickname for a female’s genitalia. specifically, a jewish “taco”.
joe: hey jeff, did you get to see the jaco last night?
jeff: naw, she was all uptight and kept talking about money.
a type of a taco, in which the meat is heavily seasoned with oregano, and topped with ketchup. named for a former roommate, josh, whose family might possibly have invented this idiosyncratic blue-collar italian variant on the most mainstream of mexican dishes.
“why the h-ll does it smell like chiles and spaghetti in here?”
“oh, looks like my roommate’s been making his famous, weird–ss jacos.”
“what the h-ll is a jaco?”
“here, try”
“not bad. but who the h-ll puts oregano & ketchup in their taco mix?”
