An extremely British way of saying "basically", "in a sense", "in a way", "in a manner of speaking", or "idiomatically", almost always used at the end of a sentence. It's often stuffed into a conversation when the speaker is having a difficult time expressing what they really mean in precise language, and it can take the place of "um" when used habitually to keep words flowing in the absence of thought.

It means "in fact, if not in deed." The statement to which it applies may not be the literal truth, but it's not far from it.

sort of; in a way; as if it were true

a phrase used to sound cultured, especially when fellating a horse.

Oops, I just spoke an inadvertent double entendre and I want you to believe that my mind is dirty enough to have realised it but not so dirty as to have done it deliberately

This is what unfortunate people add to their sentences when they are desperately trying to convince you that they are either telling the truth or are quite a bit smarter than reality.
