I recently came across this usage “we Macgyver…” and the use of the upper case caught my attention. I googled the word to see if it is mentioned in the dictionary; Wiktionary gave me this result, for instance:
MacGyver (third-person singular simple present MacGyvers, present participle MacGyvering, simple past and past participle MacGyvered)
(intransitive) To assemble or repair something by ingenious improvisation, using everyday items that would not usually be used for the purpose.
- Our car broke down and we didn't have any tools but Jim MacGyvered it with some toenail clippers and we were able to limp to the service station.
- No place to climb? MacGyver your own set-up in a power rack for rope pull-ups or rows.
I googled the word google as well, here is the result:
google (third-person singular simple present googles, present participle googling, simple past and past participle googled)
1. (intransitive, cricket) To deliver googlies.
2. (intransitive, cricket) To move as a ball in a googly.
Now, both words are proper nouns, but “google” is not capitalised whereas “Macgyver” is.
