sawsum
Awesome. It is never actually used to mean awesome initially, but becomes it based on a mis-hearing. (see example)
"That's awesome"
"Did you just say 'That sawsum?'"
"No, I said 'That's awesome.'"
"Oh, because it's pretty sawsum too."
"Did you just say 'That sawsum?'"
"No, I said 'That's awesome.'"
"Oh, because it's pretty sawsum too."
