Do you mean...
Did you snag me at an inappropriate juncture?
Did you accost me at the wrong moment?
Did you grab me at an improper instant?
Did you nab me at the incorrect point?
Did you seize me during an erroneous period?
Did you clutch me at an unsuitable phase?
Did you capture me at a fallacious interval?
I guess yes or no based on how lazy/entertaining you find this.
Short Answer: If you're herpes, then solid yes. Never a good time to catch herpes, 'cause herpes don't never go away.
