Term also applies to breasts with larger/longer nipples. The idea is that hanging sinker weights over long periods of time will stretch them and make them longer and possibly more sensitive.
The bane of musicians all over the world: a music stand that sinks by itself, caused by stripped threading inside the bore of the stand.
John, get yourself another music stand. This one's a sinker. The conductor'll keep on badmouthing you 'cause you'll wind up staring down at the music and not at him!

Sinker
The hangover that occurs later the next day. Usually, the effects of the alcohol don't leave until late morning, leaving the afternoon to feel sick.
I went out last night and drank so much that I woke up still a little drunk but I'll be experiencing a sinker later today.
