It would seem it's equal to "fucking." Based on the lyrics for The Dresden Dolls' "Sing," where some half-deaf music downloaders posted the lyrics as being "There is this thing that's like fucking..." when the booklet and song clearly say "There is this thing that's like touching."
"I was totally fucking a boob..."
"I mean... touching. I'm a 12-year old dumbtouch..."
The act of engaging in physiscal contact with an object and or thing.
"Mommy, gods touching me again."
