Another "slang" question
This is one I saw while watching Chasing Shadows. But of course their board is basically dead now, so I came here to ask.
During the plot of one of their episodes, one character had been arrested or accused of "Fly (something)." Then later, the detective ended up at a junkyard with a big sign on it saying "No fly . . ." Argh! I forgot the last word! Something with an -ing and "fly" is the adjective: No fly fishing? No. No fly chasing? No. No fly digging? No. What was it?
Anyone here who can help complete the phrase AND tell us what it means?
