when all boys are that age, and haven't seen a vagina yet, they do that and it is supposed to resemble a vagina, and its kinda funny/weird at the time, but now looking back on it it's extremely hilarious that CH was able to capture the essence of my youth with such an accurate portrayal of what it was like at the time, and its just an overwhelming sense of deja vu, and it's just the best thing ever.
