human vs google

how do you know who to trust when faced with human info against results from google?

i guess you usually go for source, but what if both sources are reputable?

here is my dilemma. a welsh person told me some hilarious words in welsh however, google translate doesn't quite agree. but i think computer translators aren't yet up to scratch so i'm going with human winner in this battle. you'll be pleased about this because you'll now find out these two hilarious words in the welsh language. i will spell them phonetically, partly because i don't know how to spell in welsh.

1) jellyfish, in welsh, is called a:
piss god wibbly wobbly
(i think pysgod is correctly spelled welsh for fish, but i prefer my spelling)

2) microwave, in welsh, is called a:
poppity ping

anyway, that's enough learning for one day.

cheerio.
