To "swab," or wipe, someone's stuff with your dick. Usually done to coffee mugs, toothbrushes, and other items that, when you tell the owner about the dickswabbing, will induce vomiting.
Note 1:Dickswabbing has a military connotation and possibly a military origin.
Note 2:Dickswabbing is in no way a name for fellatio.
"What a douche, just sipping on his coffee while we clean up his mess."
"We already got our revenge; I totally dickswabbed his coffee mug last night."
"And I kidnapped his dog."
