A quite old yet funny game to do is "Word Chain", and it's simple:
You say a word, and the next person has to use the last letter of that word as the first one for his word.
English > Haemorrhages > Super > Revolution
Sounds easy, right?
The limitations however are that you may not use names or abbreviates, and they must be in the dictionary. Another nice thing to have is that you'll avoid extremely long words such as LlanfairpwllÂÂgwyngyllgogerychwyrndrobwllllantysiliogogogoch, Pneumonoultramicroscopicsilicovolcanoco niosis or supercalifragilisticexpialidocious(dear god how was this created)
The same word cannot appear twice, while that is going to be tough: I don't mind if it happens.
Do not use any offensive language.
Let's see how long the chain will get.
