The sound a horse makes instead of a neigh, at least according to Spongebob Squarepants.
Found in the episode My Pretty Seahorse, where Spongebob finds Mystery the seahorse.
Mystery: neighhhhhhh
Mr. Krabs: What was that?
Spongebob: Just practicing my impression of Mystery, Mr. Krabs! Weesnaw!
Get the weesnaw mug.
