To be exceedingly happy and content.
The full phrase is "happy as a clam at high tide." Clams can only be dug up at low tides, so at high tide a clam is safer and secure, so therefore, happy.

When a girl charges at you with her vagina with such ferocity that it may as well be a charging rhinoceros. Common activity of women who are normal in large groups but go feral when alone with a guy they want to have sex with. Women who collect stamps and have more than one cat often go in to rhino clam mode.
Oh shit, here comes bridgett. Fucking bitch tries to rhino clam me whenever we get within 50 feet of each other. Thinking about telling her I am gay, but with my irish luck, I will probably end up with a closet rod in the ass.
