F word (F**K) is a common bad word using in advertising agency (mostly international or establish)... example..
my first training at Arena Advertising.. their art director "F**K!! i thought u already gave to her!" he angry with their client servicing
my first agency i working at Azan Media my boss said " Dont give a F**K to me!!" - he's angry when their staff coming late coz lepak2 dulu at mamak..
my current agency.. my creative director "syafiq!! what the "F**K r u doing.. u wanna responsible with this??!!"
my art director "where's the file??!! which one??!!.. this!!!???.. this is the wrong file u edited...F**K!!! Shitt!!!
my copywriter "what the F**K he's thinking??!!"
sometimes its comes suddenly one of the staff... "F**K!!!" (middle in the silence creative department)...
when i got shouted with my boss.. in my mind.."C***I!!??" (mine is different).. hehehe
