7. Decizia arbitrului l-a scos din pepeni
The referee's decision pulled him out of his watermelon patch (made him angry, made him lose his temper). Apparently this refers to the fact that the guard watching over a watermelon patch had to shoo away people who wanted to steal some of the fruit.

10. Decizia lor e frectie la picior de lemn.
Their decision is a rub on a wooden leg
11. Frecam menta
We're just rubbing the mint (wasting time). Ancient Greeks used to rub their dining tables with mint to refresh the rooms. It appears the custom lasted throughout the centuries, for when Phanariote Greeks — from the main Greek quarter of Constantinople, Phanar — were appointed rulers in Moldova and Wallachia starting in 1711/16, they brought it with them. Soon throughout the Phanariote period (which lasted until 1821) and beyond, wealthy families had some of their servants rub the mint every day, and some of these servants liked the easy chore and made their best to do it for hours so as to avoid more strenuous tasks. It has thus come to be associated with indolence, pretending to work, wasting time . . .
12. Era o liniste de puteai auzi musca
It was so quiet, you could have heard a fly buzz
13. Se simte cu musca pe caciula
He feels he has a fly on his hat (guilty). This probably stems from fairy tales. I remember one where a bee landed on someone's hat to indicate to the protagonists something, possibly that the person was guilty (I'll have to look up that story again).
14. Tragi de timp
You're pulling at time (playing for time, stalling)

19. Om traim si om vedea
We'll live and see
20. Au facut din tantar armasar
They made a stallion out of a mosquito (made a mountain out of a molehill; the words "stallion" and "mosquito" are chosen in Romanian because they rhyme)
21. Au lasat-o in voia sortii
They left her to the will of fate
22. Si-a unit soarta cu a lui
She tied her fate to his (cast her lot with him)
23. Acum traieste la mama naibii
She now lives at the devil's mother's (far away)
24. Ii lipseste o doaga

It's clear as a tear: you've found someone else
26. Poti sa-ti pui pofta-n cui
You can hook your desire on a nail (you'll have to give up on something you really want). The Romanian pofta can mean desire, appetite, appetence, eagerness . . .
27. A facut-o batand din palme
He did it clapping his hands (quickly, without effort; you may think it means to order someone else to do something for you, but it doesn't)
28. A facut din rahat bici
He made a whip out of s**t (to achieve something notable with modest resources; sometimes used to mean that it's possible, that he really did it, and at other times to disparage his achievement, for you can't make a whip out of shit and make it crack [which is the lesser-known the extended phrase])
29. E un rahat in ploaie
He's a s**t in the rain
30. Minte creata!
Curly mind! (used to address someone who may think he is smart but whose ideas are, in fact, rather stupid; it most likely has to do with the circumvolutions of the brain, but is used disparagingly)
31. A cazut din lac in put
She fell from a lake into a well (from the frying pan into the fire)
