So it's come to this - overheard on a bus

Male student: ..I'm not liking this new job, I get oil all over my hands
Female student: You want to get some Swarfayga
Male student: What's that then?
Female student: It's not very nice, like green jelly, smells funny, but it gets oil and stuff right off your skin
Male student: Where'd I get that from?
Female student: Any cleaning shop. Swarfayga, s-w-a-r-f-e-g-a
Male student: Yeah, I'll get some of that then, I need some of that in my house
