I recently had a discussion with a colleague regarding the phrase "a drop". We came up with the following two examples:
Can we change the meeting to a drop later?
Can you move the tab a drop over?
I thought the questions sounded okay, yet my colleague had never heard of the phrase used in such a manner.
In the two example, "a drop" is basically used as a substitute for "a little" or "a bit". It may not be the best word choice, yet is it okay to use "a drop" in such a manner?
Are these sentences grammatical? Is this kind of usage of "a drop" considered slang?
