Usually a girl, commonly found playing online games.

With all the qualities of a normal wallflower, this type of person is seemingly shy with low self-esteem, soft spoken, with average attractiveness.

Because they seem like such a decent person, you have no qualms about sharing your life story or dickpics with them.

HOWEVER. Once you're lulled into the false sense of security the poisonous wallflower projects, they viciously use this information against you in various ways that aren't always apparent.

How to spot a poisonous wallflower:
-Has many friends of the opposite gender on the internet, because at heart, they're an attention whore
-Deems themselves 'awkward', yet is able to spot a social faux pas easily
-Soft or quiet voice, uses a lot of flowery language to cover up their ill intentions
-Easily forgivable
-Has extensive knowledge of 4chan related things, yet seems very innocent
-Curses a lot when typing, but usually not over any voice services such as skype or teamspeak
-Adept at leading people on

The best way to deal with a poisonous wallflower is to deny them attention, namely blocking or ignoring them. If you try to show the world their evil ways, they'll turn it into a "victim" situation, where you're the one in the wrong.
Neil: "Sara is actually pretty cool for a girl gamer."
"Don't fall for it bro, she's actually a cold-hearted poisonous wallflower who will pretend she cares about you before casually admitting she hates you."
Neil: "Nahh dude, she's chill I swear."

Two weeks later, Neil committed suicide.

When you're so damn sexy that even when you're a wallflower at social events, people still come to holler at you, thus you are wallflower-proof.

The act of collecting every last wallflower at a school dance or prom, cramming them into a van, sometimes (not always) involving several people making out with each other at any given time, typically lasting until the wee hours of the morning (or whenever curfew comes into play).
*NOTE* Wallfowers tend to have more dignity, or at the very least, be considerably more shy than the average "date". For this reason, Wallflower Orgies NEVER involve sexual intercourse, regardless of what the name may imply.
Ok, so Nick may have been a total nerd, but that wallflower orgy he had made me pretty jealous...

When someone flirts with unpopular people just to get attention.
"It's all false love and affection, you don't want me, you just like the attention", is a good way to put it.
