"Blow it in" or "Shove it in" (This is a casual/rough imperative form of the verb ぶっこむ (bukkkomu), which means to thrust, shove, or insert forcefully.)

My childhood friend got a boyfriend. He's her fifteenth boyfriend total. I see, how wonderful. I understand she's happy, but why is she reporting this at my house? What happened to the boyfriend? Did she get tired of him thirty minutes after he confessed? Oh well. ※I attempted simultaneous publication with Kakuyomu.
