Yellowback 

Typically found in the UK, yellowbacks are so named for their fluorescent or “High Visibility” jackets and can be seen “Working”, usually for a local council, on many, if not most, roads in the country holding up traffic whilst supposedly there to start digging it up at some point to make sure your taxes all get spent for the financial year.

Usually middle aged, bald (either naturally or by choice), heavily tattooed and overweight, yellowbacks like to smoke (invariably roll up’s), drink tea and shout- which is not usually necessary as their power tools will rarely be turned on.

Due to Health and safety legislation, it can take up to twenty yellowbacks to perform even the simplest of tasks such as turning round the “Stop” and “Go” signs or sitting in gritting lorries eating sausage rolls. Despite the unisex “Staff working at rear” warning signs on such vehicles, nobody has ever seen a female yellowback.

Bob: "Them roadworks have been going on every day for weeks!"

Phil: "It's the council's fault! They're too tight to pay the yellowbacks night wages!"

Yellowface 

1. Refers to the practice in cinema or theatre of a non-Asian (typically white) actor/actress playing the role of an Asian character. More specifically, it refers to the use of makeup and prosthetics to give the actor a "more Asian" appearance; also, actors often affect a heavy accent and/or speak in poor English. Related to "blackface."

2. By extension, can mean the practice of taking on an ethnically stereotypical persona; metaphorically, an Asian actor may be "donning yellowface" merely by portraying an Asian character in an exaggerated and/or demeaning fashion.

1. In the infamous "Fu Manchu" series, Swedish actor Warner Oland, as well as actors Boris Karloff, Christopher Lee, and Peter Sellers, donned "yellowface" to portray the villainous, fictional Chinese title character.

2. Although "Madame Butterfly" stories usually feature a woman of Asian heritage in the role of the Asian female lead, the Asian actress can arguably be accused of being in "yellowface" by portraying such a stereotypical and unflattering character.

yellowjackets 

An often small and rather persistent (read: annoying) wasp that flourishes in the summer months and is easily recognized by the yellow portion around its midsection (the "jacket").

Yellowjackets buzzed around the table and ruined the barbecue.

yellowcake 

Concentrated Uranium ore. Can be reprocessed into uranium gas, which is a feedstock for uranium enrichment. Enriched uranium can be used in nuclear weapons; at low levels can be used as fuel for nuclear energy plants.

Guard at the Isfahan Nuclear Conversion Facility in Iran: Look at all that yellowcake in the back of that truck, i hope it isnt used to enrich uranium.
