A hot lunch is a child who is born to two parents following their divorce. In order for that child to be considered a hot lunch, the parents must have at one time been married and be separated or divorced at the time the child is conceived. A hot lunch is essentially the opposite of a bastard.
My friend Nicola is a hot lunch her parents divorced and then they had after they were separated.
The stuff you pay for at school or potentially the grossest fucking thing people do during sex ever. Holy fucking Jesus Christ!
I can't even explain this in a sentence because hot lunches are gross. That goes for both of the definitions. Man I can't wait to leave hot school lunches behind!
