(Agree with the first
def, but want to embellish.
Type thing is an expression of normalizing things, suggesting that
everything is "as usual."
(Added to the end of a word or phrase as if it is a punctuation
mark).
My anger management instructor
said "type thing" after almost
everything she said. It made me feel more comfortable in class.
Examples:
"The restrooms are located just outside this meeting room, type thing."
"From this course, you
will learn helpful new tools, type thing."
Other examples:
"My car was dirty so I went to the car wash, type thing."
"Let's go out tonight for dinner and a movie, type thing."
