Weird Creep on Exit 68?

So I moved to Palm Beach County for a job in November (live in Lake Worth Beach, work in WPB). One of a few different routes I take to get to my job has me getting off I-95 at Exit 68 (Southern Blvd), and I've noticed this one specific guy who hangs out there most days, either near the northbound exit itself or on the median between lanes when you turn left onto Southern after exiting. It's an older guy who doesn't seem to be homeless (he looks generally clean and has multiple outfits I've seen him in), but is a complete fucking creep.

All of the shirts I've seen him wearing have slogans about eating ass and/or pussy and sometimes photos of women's asses, and he regularly sexually harasses drivers. I've seen him doing weird suggestive dances, taking his shirt off, and outright making blowjob motions whenever a woman driver has the bad luck to be in the lane closest to him at a red light. And this seems to be all he does. There have been days where I leave my apartment before 8AM and leave work after 5PM and he's just been hanging out there all day. Anybody who's been in the area longer than me know what the hell is up with this guy?
