Fum

Acronym of "Fucked-Up Man"

For use when:
a) Girlfriend dumps you for cheating with her cat. (wait... WTF?)
b) Caught stealing (free) unattended samples at the supermarket.
c) When you drink toilet water soup, made by your 4-year old.
... or whenever you get fucked (at school, while driving, on the mattress, etc.)

I am officially a fum.

God, he is such a fum.

fumming

The act of being fummy. To bludge. What one does at work after Friday's pub-lunch. Doing bugger all and dragging everyone else down with you.

Another, less common, form of fumming involves sitting next to a colleague while he is on the phone to a customer and scrawling all over his notepad whilst giggling. The notepad should end up containing a crude caricature of the colleague's sister with the words, "Please wear pants to my party" in a speech bubble. This slightly more obscure form of fumming can often be the most effective as both parties usually end up imploding in a fit of giggles.

The Letter M: "So, Soulless Ginge, what have you done today?"
Soulless Ginge: "Nothing mate. I've been fumming all day today."
The Letter M: "Okay. Let's sit around with Angry Italian and make knob jokes."

Fum

When a male reaches orgasm and begins to ejackulate into their mate. Suddenly a uncontrollable release of gas from the anus is released with each ejackulate squirt.

Male: sorry babe. I fumed again.

Female: yea, that was weird.
