Oh, we have many weird sayings. Just a few:
"Vén kecske is megnyalja a sót" translates to 'Old goat also licks the salt' means that older people can still be into romance and other stuff, too.

"Kevés vagy mint Mackósajtban a brummogás" translates to 'You are as little as the roaring in the Teddy cheese'. The mentioned Teddy cheese - Mackósajt is a Hungarian cheese. Means you are useless or not 'enough' to do something.
"Miért itatod az egereket?" translates to 'Why are you giving drinks to the mice?' means 'Why are you crying?'
"Majd ha piros hó esik" translates to 'Only when red snow falls!' We say that if something is impossible.
