The adjective more is not superlative
1. impinge = strike
The word impinge can have various meanings, but in the case above, it means to strike. When 'the rain impinge[d] upon the earth,' it means that it started raining, the rain started striking the earth. To impinge means that something starts, and usually something negative.
2. garrulous = loquacious
The word garrulous refers to someone who talks excessively, likes to talk a bit too much, and usually about something trivial. Loquacious is a fancy word to denote the same thing, although it has a more positive connotation - it refers to someone who can speak nicely.
3. pious = religious
The word pious comes from the Latin word pius, which means dutiful. So when English took this word from Latin, it added a different suffix (-ous), and gave it the meaning of being 'dutiful to God.' So nowadays, pious refers to someone who is devoutly religious.
4. ruinous = dilapidated
The word ruinous refers to something which is in ruins, which is falling apart. The word which means the same thing is dilapidated - both of these words are usually used to describe buildings that are very old, and derelict, and are practically in ruins.
I'm not sure if you meant baking or biking but if you meant biking then it basically means it's unsafe and one you get in an accident your brain would uh fall out so yea.
The best revenge is to just happily move on and let Karma do the rest.
