I'll go either way. If I think the table is very aggressive, I'll mock tilt for an orbit or two, hop to get a great hand, and shove with it looking like an angry spew. This has worked out nicely a few times.

But most of the time, I just go with 'well played, nh'.

Him : Terrible play
Me : Yeah, Limp calling with a weak K is pretty bad but don't be too hard on yourself.
LOL
