Angel-wing like pattern created on sheets, furniture, or other upholstered material by sweat on the bottom partners butt during extended and/or vigorous sexual activity, especially of the cowgirl and reverse cowgirl variety.
Named for its similarity to imprinting the pattern of your moving arms and legs in snow to create a "snow angel".
Example 1
Girl 1- Whoa, you got a tattoo without asking your parents?
Girl 2- Yeah my parent's are going to kill me and my older brother who signed off as my guardian.
Girl 1- Looks like you guys have gotten yourself into a pretty bad buttweave...
Example 2
Boy 1- Andrew is such a buttweaver; everything he says makes people uncomfortable.
Boy 2- Dude yeah he really needs to learn how to act like a normal person.
A long wooden stick with a point on the end for people to scratch their butts. Similar to the backscratcher. Peter Griffin from Family Guy sold Buttscratchers at sporting events to pay for Chris's tuition in "No Chris Left Behind".
Peter usually holds one up and says to the crowd "Buttscratcher?" Usually someone answers back saying "Buttscratcher!"
Very funny to say in real life. Never gets old. Ever.
Peter: Buttscratcher? Buttscratcher? Get your Buttscratchers here! Buttscratcher?
