I've been reading tab from a new tab book i got and i've came across the term "grace notes". Can somebody pls tell me what they are and how to play them on guitar. Thanks

an example would be helpful.

is it labeled as... |--5--(5)--| ... or something like that? That usually means to sustain the first note for twice as long.
theyre jus notes that hav no time jus like a really fast pickup note

You need to douse it in a 20/30/50 ratio of mustard/ketchup/horseradish and stroke it as fast as you can untill the mayonaise squirts out. Then consume.
It's a note that doesn't have to be played, they're usually written slightly smaller, and maybe in parentheses. They're just little accent notes that you only play if you can, but you don't have to.
grace notes are pretty much just notes that happen before the actual beat.

Sometimes I pull down my pants and play slap bass with my schlong. So I guess thats pretty important as well.
