as said in the beginning, some of the english words used are not meant to be pronounced as their actual pronoucation, the "tekan" word is a malay word and the closest meaning i can explain is to get punish
"chao keng" the chao is not pronounce as "chaos" it is a hokkien(some chinese language) word, and "chao keng" means to slack off or be lazy for the closest meaning i can explain
