verb (yak, k, ing)
- An ox-like mammal native to the Himalayas and Tibet with dark, long and silky hair a horse like tail and a full bushy mane.
- To talk, particularly informally.
- To vomit, usually as a result of consuming alcohol.
Note: This is subject to the typically Australian 'have-a-verb' syntactic construction, as in 'I had a yak last night'. But this does not qualify 'yak' to be nominal.
