stupid question but do trolls say each other's names in their own quirks?

Yeah, as an example in [S] Past Karkat: Wake Up, Terezi uses 4R4D14, T4VROS, K4N4Y4, 3R1D4N when talking to those respective characters as well as using K4RK4T, N3P3T4, T3R3Z1, VR1SK4, G4MZ33 and F3F3R1 on multiple occasions
