Some languages have built in moods and modes.
Malayalam is satvic and even 'gaaliaan' won't sound harsh! :yawn:
Tamil is OK with neither too much harshness nor too much softness in its 'gaaliyaan.
In Telugu even respectful words would sound like 'gaaliyaan' since they use the
'ka', 'cha' , 'ta' /'da', 'tha', pa', 'ra/Ra' known as 'vallinam ' alphabets too much.
thandri ( father), koduku (son), Kodalu (D.I.L), Vadina, maradalu,
aadapodusi (S.I.L ), alludu ( son in law), thammmudu (younger brother)
are all made up of the 'vallinam alpahbets.
So even normal talking sounds harsh. So need to elaborate on the scolding
worlds. In addition to all these they have fiery temperament - thanks to all
the red hot chillies they consume with their boat shaped and boat sized
aavakkaai pickles! 
Often I wonder why Bharatiyar referred to it as Sundarath thelungu!
