The term "interweb" is a combination of the words "internet" and "web." It is usually used humorously or sarcastically by someone who is knowledgeable about technology, but not by someone who is familiar with the internet or technology in general.
For example: “How do I send my email to the internet?” Because of its humorous connotation, the word “interweb” is often used in memes.
Below are some examples of where the word can be used:
Interweb is sometimes spelled interwebs, interwebz, or intarwebs to emphasize some people's ignorance of technological concepts. You'll also see the word used in a phrase like "teh interweb," where "the" is deliberately misspelled to further mock the person being talked about.
