In the case of Morgana, that seems like an unlikely scenario.

In the case of Drasil... Yeah... He seems like the type who'd totally do that.

Leaving ghetto-Drasil aside for a bit though. Has anyone noticed how isekai-protags in anime always seem to use that sort of lingo in the english dubs? Just take Slime-anime and Rimaru as an example. I find it very amusing.  Too bad we don't have any hard-core rapper MCs in our cast. :p
