It’s a long time since I went out on the razzle, but your birthday will be a wonderful excuse.
我好久没出去找乐子了，你过生日倒是一个好借口。

On the razzle
"On the razzle" is a euphemism often used in the British press to describe the actions of a celebrity who has drunk, or is about to drink, a considerable amount of alcohol. A night "on the razzle" does not carry completely negative connotations; it is only used to describe someone as having enjoyed themselves.
