I was assuming this was a typo and was thinking about making a joke about it, but it does appear to be slang that fits the context:
https://www.urbandictionary.com/define.php?term=Truggle
> 1. the standard of perpetual intellectual failure made by an individual.
> Truggle; the standard defenintion of a person who is a failureat everything.
Was it a typo or did you actually mean this?
