Phil must really want to get the point across that he's shouting with joy everytime he's using them. This obviously can't be right, he definitely uses them incorrectly and not the proper way they're intended to be used.
He even uses them in a parentheses as well (which btw Phil, is not used to shout a similarly worded response, but to fill in gaps of a passage that wouldn't make sense without an explanation). It appears to me that he uses them to sound as overly enthusiastic about something that happened moments ago as possible, you don't even need to know his reaction about what he's talking about on his streams and later see them translated in a tweet, you can easily pick them out and see for yourself that he butchers them.
And yeah with the latest tweet he just posted, you don't need to use this many...
"Great stream of Hades tonight! I indeed did clear the game a 9th time (This time with the gauntlets!) and started up a 10th and final run with the HIDDEN ASPECT of said gauntlets. Next time will likely be the conclusion! Thanks to all who chilled, I'm now uploading to DSPGaming! " - DSP
