Here's what you do... 
sit directly across from him, 
make eye contact, 
and play footsie with him under the table.

put your foot on his crotch. 
just make sure you make it clear that you're the one in control.

control. 

if he retracts his foot out of disinterest, 
smash his crotch with your foot.
