vb. (present participle of go Dutch English)
Wikipedia
"Going Dutch" is a term that indicates that each person participating in a group activity pays for themselves, rather than any person paying for anyone else, particularly in a restaurant bill. It is also called Dutch date, Dutch treat (the oldest form) and "doing Dutch".
There are two possible senses—each person paying their own expenses, or the entire bill being split (divided evenly) between all participants. In strict usage, "Going Dutch" refers to the former, paying one's own expenses, and the latter is referred to as "splitting the bill", but in casual usage these may both be referred to as "going Dutch".
A derivative is "Sharing Dutch", which stands for having a joint ownership of luxury goods. For example: four people share the ownership of a plane, boat, car or any other sharable high-end product. This in order to minimize cost, sharing the same passion for that particular product and to have the maximum usage of this product.
