10 year old: Yay, my Charmeleon evolved into a Charizard
Horny teenager: Are you talking about the pokemon or the act in which a man lights a girls pubes on fire
10 year old: What? I just want to beat my rival's Venusaur
Horny teenager: That means to insert a bonsai tree up a woman's vagina.
10 year old: Oh My God! That's just weird! I knew I should've chosen Squirtle.
Horny Teenager: Oh yeah, to Blastoise
someone means to squirt water pistols up their vagina and anus at the same time.
