1. Literally, to compel or physically force someone to swallow something. I hate how doctors try to force pills down your throat for even the tiniest of colds. The government has come under fire for ordering prison staff to force food down the hunger strikers' throats.

2. To force, compel, or attempt to make someone accept, endure, consider, or agree with/to something. I hate going to my friend's house, because his husband's always forcing conservative rhetoric down my throat. Look, I'm just browsing around for a car—quit trying to force one down my throat!
