To jibe with someone is to agree with them. Jibe can also mean “be compatible with or similar to.” If two people jibe, they get along quite well.
A jibe can also be an insulting remark as another way to spell gibe. If someone directs that kind of jibe at you, the best response is a really good comeback. And in nautical terminology, jibe refers to a particular manner of changing the course of a ship. How did this word come to have such different meanings? Your guess is as good as ours. Just try to remember that if you want to jibe with others, don’t insult them.
