Idek - Engineer 2 | MWB Solos 

[LYRICS]
You’re not gonna win this fight because you are trash
I mean, how did you lose to Mario?
(beatbox freestyle)
I mean like sure my round one was trash,
but at least I had a chance of winning compared to you
(Beatbox freestyle)
Now you are going to face the wrath of engineer (2x)
(beatboxing until the end)
