Can't get the meaning of "score mondo points" [closed]

I'm stuck with understanding the following sentence from Effective Modern C++: 42 Specific Ways to Improve Your Use of C++11 and C++14

yes, the syntax looks toxic, but knowing it will score you mondo points with those few souls who care.

1. What are these mysterious "mondo points"? I googled it and it relates to shoe size which seems kind of weird.

2. Do I understand correctly that these points are represented by souls? I also found that there is a phrasal verb "score with" which means to please somebody or someone. So in this case, knowing will score with (please) few souls and you is now irrelevant?

Solution 1:

Mondo is slang for very or extremely. The entire sentence is very informal and has some other elements of programmer jargon or slang.

Re-written more formally, it would be:

yes, the syntax looks bad, but knowing it will get you a lot of credit and appreciation from the few people who care.

mondo (MW)

extremely (slang)
