Ive been reading on this forum for about 2 months now. I keep hearing the term "Tank slapper", what is it?

 

either you come down from a wheelie crooked or on a stoppie you get real high and the weight of the bike makes the handlebars bounce out of control from side to side. when you have your first one, dude you wont forget it. laters

 

just wheelie and come down with the bars crooked and you'll find out. most of the time you won't crash but you'll **** yo pants

 

happens to the best of us so watch out
