Not sure of how to get your message accross? You cant exactly send flowers to say “I hate your fucking guts” or “just fuck off” – if youre looking for a generalised action to cover a range of emotions, I suggest the Middle Finger. For example:

Boss: Where is your name badge today? You know next time this happens… [insert long lecture of work ethic and correct uniform] … ok?

Random Dickhead: Hi, my name is [Tool], do you come here often? I havent seen you around [Im a tool Im a tool Im a really big tool]

Prior friend aka bitch: Omg, so the other night wah wah wah, and then blah blah my life is so horrible and my mum has a shit job. W.A.H.

People who are just annoying for fuck only knows why: [insert any annoying actions that come to mind - there are too many for me to list so use your imagination I cant do everything]

So, next Mothersday, Fathersday, Public Holiday, to the next wanker that cuts you off on the road or in a conversation, to the fuckwit that just wont shut the hell up -

Cheers.
