Yellow Sack 

Having a pimple so large on your ball sack that it appears to be a third yellow ball. The surface tension is so tight that very little pressure creates a yellow eruption of ball puss.

Last time Longinus needed me to pop his yellow sack,I got a fowl sour yellow explosion all over my face and I nearly passed out due to the smell

Yellow bellied Sack Sucker 

A creature from the Roberts family in the Genus Micheal. The yellow bellied sack sucker is a creature of the night. Found in dark alleys sucking only the dirtiest smelliest sacks. If you make eye contact with this creature you could vomit from its nastiness.

I was walking home last night from the bar when I saw it! “The yellow bellied sack sucker” was grunting and sucking so many sacks! It was terrible!

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.

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!"

yellowjacket 

n. a large plastic ramp-like object laid across a doorway to provide a walking space over cable equipment, such as in a stage set, especially where the amount of cabling makes gaffing impractical (so named for their common colour)
