11 new collective nouns

A collective noun is a word used to define a group of objects. For example, in the phrase ‘a pride of lions’, pride is the collective noun.

Here are some that I reckon should be added to the official list:

1. An ambush of salespeople.
2. A gush of sycophants.
3. A hatchet of restructures.
4. A huff of exes.
5. A google of geeks.
6. A lechery of priests.
7. An absence of waiters.
8. A flounce of teenagers.
9. A nag of inlaws.
10. An ulcer of deadlines.
11. An excess of bloggers.

Do you have any to add?
