Okay! Don't panic and stay calm. This has happened to even the most experienced vaporers so there is nothing to be ashamed of.
You have come to the right place for this premium liquid emergency (
CRACP). Other wise known as
Casa
Recover
And
Containment
Proceedure
First - Restrain all pets, small children and old ladies. You don't want their saliva to mix with said Casa.
Second - You failed to convey the extent of the Casa injury and too which sleeve so we must assume it is your RIGHT arm sleeve that has stepped out of line and assaulted your Casa. This kind of action must never be ignored. Such violent and uncalled for behavior of any sleeve must never be tolerated and must be dealt with immediately and with unwaivering force.
Third - With the assistance of your gf you should move your right arm toward the center of body. Then carefully begin to rub any excess Casa off from the assailant (your sleeve) onto this "center section" of your body. Ideally this area is located just below the belly button.

With steady even pressure you will want to continue this rubbing motion until most evidence of the victim (Casa) has been dispersed onto this area.
Forth - At this time you will want your gf to resume her original medical procedure you had described to the newly transfered "area".
Fifth - While she is busy working on that procedure you will want to remove your shirt and begin sucking your sleeve to recover all remaining traces of said Casa.
Sixth - Emergency situation has now been resolved and you may now address any other situation that may have arose during your Casa recovery and containment procedures listed above.
