Torie, before I read about Marc and the Genital Warts thing, I was going to suggest that you go out, buy condoms, and 2-3 hours after he leaves, back him into his room and Rape him.
You could then explain what a True Shit Lisa is while you have his Full erec…attention.
Sure, its a little cold, but I knew he was a really good friend from what you said and I thought that if you had to ‘take one for the team’, he wouldn’t be the worst candidate.
The warts complicates things a Lot. And as he’s been banging at Lisa’s Nastyness, you must now assume he could well be infected. That and as a friend, he better expect a BIG fight over his behavior.
First Things First: Make sure your are fully dressed. You need
(1) bat (cricket or baseball)
(1) large bucket of water (Cold)
Next: Bang On That Wall. Use the bat if necessary. Then shout, at the top of your lungs
“She Has Genital Warts, I Hope You Know!!!”
Shout it loud enough to be heard from Bristol or London. It should have the effect of a cold bucket of water. If it doesn’t, Use The Cold Bucket Of Water. Open Sam’s door and throw it on them both (have bat nearby).
Important: Make sure that in one movement you drop the bucket, grab up the bat, and grab her pants off the floor with your free and Repeat statement about genital warts, just as loud. Point with pants hand for emphasis.
As all Hell starts to break loose, back quickly towards the open apartment outside door with bat and the pants. (Do not let Lisa take them from you)
Throw pants outside apartment into the hallway. As she goes for them, slam & lock door behind her. (nudge her with bat if you need help getting the door closed)
Now, all you have to worry about is Sam.
Best of Luck, BTW…
