Huat Cai = Huat Gai Na?

this was totally spastic and retarded. "Huat Cai" is my pet phrase i like to use in school after taking it from the dota games i play with my team. everytime something interesting happens, i will just shout out "Huat Cai La" however today during the english class, i think Shaun and Alton was too bored... until they changed Huat Cai into Huat Gai Na. wad is going through shaun's head?!?! how the hell can he think of such sick substitutes for Huat Cai! i dont know =_=. then they started spreading.. that i was shouting Huat Gai Na instead of Huat Cai.. how stupid? cos i seriously meant Huat Cai.. >_< so close friends started shouting Huat Gai Na.. how retarded -_-" today's just the beginning.. T_T~!
