Yaks and Ewww are the most common expressions that a pretty and "sosyal" ladies, or a normal pretty girl use when they dont like a guy, or something that a guy said, or acted.
Ive experience this a lot, especially when i say "I really like you", then she said, "EWWWW!", mura gyud ko gi dunggab sa ko heart, diri dapita ba, sakit kayo.
how bout you guys, kasuway mu ani?
