I really like 'ting'. It's London Jamaican for a casual girlfriend.
There's a pop song by Ramz called 'Barking', and he sings about 'linking his ting from Barking' (ie getting together with his bird in East London.)
The word has other meanings too. 'Dat's mah ting' could mean 'That's what I'm doing/what I'm interested in' etc'. 'Thing' is so boring in comparison! Innit? Yeah!
