Term used, primarily by US immigration officials in informal settings, to describe an illegal immigrant of any country. Origins are unknown, but definitely predate the use of metal flashlights, contrary to the most used description of origin. It's probable that the origin is related to Chinese immigration, as the first law to restrict immigration from a particular country was enacted in 1882. It's said that many of the illegal immigrants made their way to the US via the Gulf of Tonkin area of what is now Vietnam. It's also possible that the term is related to the Chinese "tong" mob. The word should be considered only as derogatory as the phrase "illegal alien" as it does not refer to race or even nationality, only to one's immigration status in the United States.
The US Border Patrol Agent caught 3 Honduran tonks, 18 Mexican tonks and a Korean tonk when they tried to sneak across the border this morning.

Illegal Mexican immigrants.
"Tonk" is the sound that is made when the illegals are hit over the head with the large flashlights/batons that the US border patrolmen carry.

British slang word for muscular or 'strong-looking'
it has been used to describe girls as hot as well nowadays. It acts as a double for the word 'fit' :)
