我需要一些“fun express”

fun expression?

en..what about........say..if a handsome guy or a beauty likes you, but you don't like him/her, you could say...he/she is not my cup of tea...

can't think of any others right now....

some idioms just jumped into my head...

* storm in a teacup
----中文大约是小题大做的意思。很形象吧^_^

* paying lip-service
-----空谈~光说不做~

fun expressions才对。你给个例子？
