My bf is soo cute and funny and hes the nices guy i ever met but sometimes he jus really bugs me.... 1 thing he does alot is shout Honey combs big! Yeah Yeah Yeah!!! to my mom cuz she thinks its high-laries and it just really sucks........ He talks about comic and movie bull crap 2 my mom too. it really embarrased me because they have long chats about X man chars and stuff while i am Trying to make out with him. Also she alwys offers him Pizza rolls. How can i make my mom GTFO
