Tiu is a Chinese word in the
Cantonese dialect that literally means 'penis'. However, its most common use is not as a noun but as a verb. To 'tiu' someone thus means
'to use the penis on someone', or to 'fuck someone'.
Due to this usage, the word 'tiu', when taken as a noun, has
morphed to mean 'fuck that' and used in a somewhat similar way to its English counterpart.
"She wants me to pay for her
manicure? Tiu!"
"Tiu
nay low moe! I've been waiting at the club entrance for more than 50 minutes!" ('Tiu
Nay Low Moe' means 'screw your mom'. Here 'tiu' is a verb.)
