quite pleased; delighted
"I was ecstatic and my playing partners were chuffed for me. However, my friend who lent me his clubs is claiming that half the hole in one is his!" Tim Fox, quoted on Worldgolf.com, June 13, 2011
About the Word:
Chuffed comes from the English dialect word chuff, meaning "pleased; puffed with fat." In current usage, the fat is gone and the pleasure remains.
