He's got love handles.
Fancy a bit to eat.
Be a bit peckish.
I don't know what these sentences mean, I was confused, so do my teacher.

So, my friend, I need your help!
'love handles' means the middle-age spread, the excess fat around your waist.
It is quite humorous and is called so because during sexual intercourse it can serve the purpose of gripping your partner firmly.
fancy= would you like
peckish =hungry or crotchety=irritable.
so is my teacher (not so does).
Thank you for your reply. And I feel a little shame for my poor grammer. Anyhow, I 'll try harder to catch my fellows.
