Freejacking means: An American actor plays a British role with such convincing accent that their audience doesn’t even know they are British. Freeaboo is the root of this word. See also teaboo and weeaboo. The “tea”, which refers to the British stereotype of people who drink tea, is used. Teajacking, which is the opposite of freejacking, can be done.
