After numerous Olya's questions I decided that I need to brush my 'everyday' English a little too. So I opened my "Super-Mini Common American Phrases Dictionary (A guide to conversation and small talk)" by Richard Spears. It's supposed to teach me "общепринятым разговорным выражениям, используемых в современном англ. яз. в США".

But some examples at the early beginning made me cringe:

- See you later.
- After while, crocodile.
and
- After while, Mary.
- Toodle-oo.

My school teacher (years and years ago) told me, that this alligator/crocodile stuff is outdated. And what's with "Toodle-oo"? Do people really use it? It sounds... well, I don't want to offend anybody, who may use it.

Should I trust this dictionary?
