My buddies' Dad would shake his head and remark about his progeny, "You're nothin' but a bunch of goddamn come
bubbles!" while he was drinking at hunting
camp. Similar to "the best part of you ran down
your mother's leg", or "I wiped off the best of you off on the curtains after banging your Mom", this were ideological put-downs the Old Man would throw out after hearing the shenanigans his kids did unbeknownst to him while they were growing up.
