noun.

Dunch refers to a meal enjoyed subsequent to lunch but prior to dinner.

Dunch should be distinguished from linner, another meal occurring in the post-lunch, pre-dinner interval, in that dunch occurs after linner, closer to dinner time.

Thus, the socially accepted norm with regard to afternoon eating agendas comprises the following progression of meals:

Lunch --> Linner --> Dunch --> Dinner

An abnormally time-consuming, large, pasty and often painful bowel movement. As a general rule, taking a dunch requires most of one's lunch break to pass loaf or loaves and finish the paperwork.

A Dunch. The late night shit you take that's a cross breed between your lunch and dinner. This bowel movement usually occurs around 12:00 to 2:00 AM and usually results in massive clogging of household restroom facilities.

Hey katie, want to meet up for some Dunch?

The meal that falls around 2-3 p.m. Too late to be lunchand too early to be dinner but more than just a snack. It is a well balanced meal. It is often substituted for dinner for those on diets and trying to stick with the rule of 60% of your meal intake should be done before 3 pm (Shaun T)
For dunch today, I had pan-seared tilapia, topped with green, yellow, and orange peppers, with broccoli and quinoa on the side. Yummy :-)

Like a douche for the bottom.
When one is acting like a douche, but a bit over the top and a bit of asshole added in. (i.e. Stop cheating at spoons, you dunch-bag!)
