1. when you bangin a chick and she takes a crap with no warning.

2. a common pronunciation of the old english name siward
1. I was bangin susy and she swiznarked all over the place it was gross

2. For certain, sir, he is not: I have a file
Of all the gentry: there is Swiznark's son,
And many unrough youths that even now
Protest their first of manhood.
