Guys rarely win prizes for gifted emotional speeches. (Unless you consider grunting a romance language.) So it can be extremely daunting to decipher when a guy’s really into you – or really into the game playing on the big screen behind you.

While the man you’re flirting with at happy hour may not leap to his feet and declare his love in iambic pentameter, his body language is actually waxing poetic. So take a cue from Olivia Newton John and listen to his body talk!

BettyConfidential asked professional body language experts to share the signs, signals and postures men display when they’re digging you. Here’s what to look for:

1. He tilts his head.

“When people are comfortable with each other, you see a lot more of the head tilting sideways,” says Joe Navarro, a former FBI profiler and author of What Every Body Is Saying. “Men tend not to do that unless they’re interested in you. So when they’re conversing with you, you can tell they’re more and more interested … because you’ll see more and more of the head tilt.”

Just make sure those sideways glances are the result of your glowing visage – not six glasses of wine.

2. He defies gravity.

Navarro describes another set of signals men send when they’re lusting for a lady as “gravity defying behaviors.” These include arching eyebrows, emphasizing with eyebrows and levitating slightly on tiptoes.

“Men do that more than women,” Navarro says. “What’s interesting is that when men are trying to impress women, you’ll see more of those gravity defying behaviors. When we care about things, we’re willing to spend more energy, and it doesn’t take any energy to remain flat footed.”

3. He opens up.

“Women often miss the obvious because they are ‘afraid’ he doesn't like them or ‘think’ that he doesn't like them,” says Philadelphia-based psychologist Doris Jeanette, author of Opening the Heart.

But Dr. Jeanette points out that it’s easy to gauge a man’s interest by focusing on how much he physically opens himself up to you. You get a gold star if a guy …

• Moves closer to you
• Leans toward you
• Points his feet towards you
• Smiles at you
• Shares something about himself with you

Hopefully whatever he shares doesn’t begin with the words, “This one time, at a strip club in Tijuana …”
