3<3 is a widget for a butt shooting out a cloud of fart. You can even make the fart emphasis more powerful by typing in more <'s like 3<<<<<<<<3 or 3<3<3<3<3<3<3 It can often be mistaken for a heart <3 widget though.

A symbol for a heart. Usually used when you type it in the space bar of the computer because you are lonely. Or used when texting that special someone. ; ) .... or when texting your mom because again you're lonely... or just really love your mom... or your mom is cool enough to understand internet slang... ANYWAY <3 means heart
You; "Hey babe <3"
Also you; "Wait I'm lonely, OKAY NEVER MIND"
