Unpleasant feeling rising, changing side of street (7)

I haven't cracked this one yet — but the brilliant team at Fifteensquared have:

EMO [t] ION (feeling) reversed (rising = upwards in a down clue), with S changed to T (the “other side” of S[tree]T). The sort of word that probably catches out second-language English speakers: it looks as though it should mean “noisy” but it actually means disgusting, and is usually applied to bad smells.
