The singer is secretly in love with her best friend Jenny. She's too afraid to tell Jenny her feelings, but confesses to doing "bad things" just to feel closer to her friend; stealing lipstick, keeping her shirts, etc. Pretty straightforward. The line "forget those amigos" refers to Jenny's past and future boyfriends, or perhaps her entourage. Her fear of destroying the friendship or being shunned prevent her from confessing to Jenny herself.
