f-ilarious 

origin: truncation of the two words 'fucking' and hilarious'
used when there is minimum time, for maximum impact, as there are only 4 syllables instead of six.
definition: something that has greatly amused you, or continues to do so, would be described as 'f-ilarious'

1. The Office (UK series) is f-ilarious. The US version however, will not be.
2. It was f-ilarious when that drunken fool started ripping down the posters outside my room last night.
3. The world can be made much simpler by using truncated words such as f-hilarious
