Entry: inbreath (n.)
In context: "Hal's tooth gives off little electric shivers with each inbreath and he feels slightly unwell."
Definition: A drawing in of the breath.
Other: I think I marked this entry because I a) loved the sentence, and b) was curious if it was in the OED. It is! Here is a nice (first) usage:
1921 R. Graves Pier-glass 26 The deep in-breath, The breath roaring out.
SNOOT score: 1
